The measure of angle A is 72 degrees. Classify this angle:

Answer 1

This angle is an acute angle.

Answer 2

Supplementary angles add up to 180 degrees. Calculate the supplement to an angle that is 120 degrees.

Answer 3

The supplement to an angle that is 120 degrees can be found by subtracting 120 degrees from 180 degrees:

180 degrees - 120 degrees = 60 degrees

Therefore, the supplement to an angle that is 120 degrees is 60 degrees.

Answer 7

To calculate the missing value of angle B, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Therefore, we have:

B + 80 + 30 = 180

Combining the like terms and simplifying, we get:

B + 110 = 180

Subtracting 110 from both sides, we get:

B = 70

Therefore, the missing value of angle B is 70 degrees.

Answer 8

All triangles add up to 180 degrees. Calculate the missing value of angle B.
*
A is 100 degrees
B is blank
C is 55 degrees

Answer 9

To calculate the missing value of angle B, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Therefore, we have:

A + B + C = 180

Substituting the given values, we get:

100 + B + 55 = 180

Combining the like terms:

B + 155 = 180

Subtracting 155 from both sides:

B = 180 - 155

Simplifying:

B = 25

Therefore, the missing value of angle B is 25 degrees.
