Question

Teo angles are supplementary.The larger angle 3° less than twice the measure of the smaller angle.Find the measure of each angle

Answer 1

Answer:

Smaller angle = 61°

larger angle = 119°

Step-by-step explanation:

let smaller angle = x

larger angle = 2x - 3

the sum of two supplementary angle = 180°

x+2x-3 = 180°

3x -3 = 180°

3x = 180° + 3°

3x =183°

x=183°/3

⇒x=61°

∴smaller angle = x= 61°

larger angle= 2x-3 = 2(61)-3

                               = 122°-3° = 119°
