Answer:

A = 50

B = 20

C = 110

Explanation:

A triangle is equal to 180°

In order to find the measure of each angle, add angle A, B, and C to get 180°

If angle A = 5x, angle B = 2x and angle C = 110 then 5x + 2x + 110 = 180°

To find each angle, first solve for x:

5x + 2x + 110 = 180° start by adding like terms

7x + 110 = 180° now subtract 110 from 180

7x = 70 finally divide 7 from 70

x = 10

To find each individual angle, substitute x with 10. For example:

A = 5x

A = 5(10)

A = 50

B = 2x

B = 20

C = 110

If you were to add A, B, and C it should equal 180°

110 + 20 + 50 = 110

5x+2x+110=180
7x=70
x=10
