# What is the measure of angle coa??

## From these considerations, what is the measure of angle BDC?

The measure of ∠BDC is 60°. We can fill the above information into our diagram. Since ∠ADB and ∠BDC are supplementary, their total degree measurement is equal to 180. Thus, m∠ADB = 180 – 60 = 120 degrees.

## Given this, what is the measure of CED?

The measure of CED is p degree. By AA rule of similarity, Corresponding angles of similar triangles are same. Therefore the measure of CED is p degree.

## Besides, what is the measure of angle r?

Therefore, the measure of angle R is 37 degrees.

#### What are the missing angle measures in triangle ABC?

It is given that ABC is a right angled triangle which is right angled at C and AC=7 inches and CB=5 inches. Therefore, the measure of missing angles in triangle ABC are 35.5° and 54.5°respectively.

#### What is Angle and Triangle?

The angle of a triangle is the space formed between two side lengths of a triangle. A triangle contains interior angles and exterior angles. Interior angles are three angles found inside a triangle. Exterior angles are formed when the sides of a triangle are extended to infinity.

#### What are the 7 types of angles?

The 7 types of angles are: right angles, acute angles, obtuse angles, straight angles, reflex angles, full angles, and complementary angles.

#### What is the central angle of a triangle?

To find the measure of the central angle of an equilateral triangle, make a circle in the middle A circle is 360 degrees around Divide that by three angles So, the measure of the central angle of an equilateral triangle is 120 degrees.

#### What is the measure of angle BAC ABCD is a square?

Answer. the angles of square measure is 90°.

#### Can a triangle have two right angles?

No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. Thus, it is not possible to have a triangle with 2 right angles.

40°

#### What is the measure of angle BAC 30?

Therefore, in this case, knowing that the angle BAC (which is the central angle) in the circle provided measures 30 degrees, you can conclude that the measure of arc BC (which is the intercepted arc) is 30 degrees.

#### Which equation can be used to find the measure of angle GFD?

Which equation can be used to find the measures of angle GFE? The measure of angle BAC can be calculated using the equation sin-1 (3.1/4.5) = x.

#### What is the measure of angle EGF?

The measure of <EGF=28º.

#### What is the measure of each angle of an equiangular triangle?

In an equiangular triangle, the measure of each of its interior angles is 60 ̊. An equiangular triangle has three equal sides, and it is the same as an equilateral triangle.

#### What is the measure of angle EFD?

Since all the angles of a kite add up-to 360 degrees, so the measure of angle EFD will be equal to: Therefore, the measure of angle EFD is 123 degrees and option B is the correct choice.

#### Which equation can be used to find the measure of angle LJK?

Which equation can be used to find the measure of angle LJK? The equation tan-1 (8.9/7.7) = x can be used to find the measure of angle LKJ.

#### What is the measure of angle BAC quizlet?

The measure of angle BAC can be calculated using the equation sin-1 (3.1/4.5) = x.

#### What is the angle of a perfect triangle?

The 3 angles of a triangle equal 180°. So if the angles are all equal in an equilateral triangle, we do 60 times 3 which equals 180°.

#### How do you find the angle of a triangle given two sides?

Example
1. Step 1 The two sides we know are Opposite (300) and Adjacent (400).
2. Step 2 SOHCAHTOA tells us we must use Tangent.
3. Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.
4. Step 4 Find the angle from your calculator using tan-1

#### What are the three types of triangle?

We can classify triangles into 3 types based on the lengths of their sides:
• Scalene.
• Isosceles.
• Equilateral.

#### What is M Angle?

The m in front of the angle notation refers to the measure of the angle labeled A, B and C (with vertex at B). By definition, the term congruent means "having equal length or measure". Figures are congruent ( ). Segments are congruent. Angles are congruent.

#### What is the measure of angle JKL?

The measure of angle JKL is 97 degrees.

#### How do I find the angle of a triangle?

How To Find The Angle of a Triangle
1. Subtract the two known angles from 180° .
2. Plug the two angles into the formula and use algebra: a + b + c = 180°

#### What is the measure of angle BAC?

Angle BAC is an inscribed angle, which means that its meausre is one-half of the measure of the arc that it incercepts, which is arc BC. Thus, since angle BAC is 35 degrees, the measure of arc BC must be 70 degrees.

#### How do you figure out angles?

The formula for finding the total measure of all interior angles in a polygon is: (n – 2) x 180. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.

#### What is the formula to find the central angle?

(arc length) ÷ circumference = (central angle) ÷ 360°
The central angle will be in degrees. This formula makes sense, if you think about it. The length of the arc out of the total length around the circle (circumference) is the same proportion as the arc's angle out of the total angle in a circle (360 degrees).

#### What is the degree measure of angle BAC round to the nearest whole degree?

The answer would be 70 degrees.
