Question

Two angles that form a linear pair are in the ratio 2:3. Find their measures.​

Answer 1

Answer:

let the angle be 2x and 3x

then by linear pair theorem 2x+3x = 180

5x=180

X= 36

then angles are 2×36= 72

and 3×36=108

Answer 2

Let the measures of the angles be 2x and 3x

2x + 3x = 180°  ( linear pair )

       5x = 180°

         x = 180°/5

         x = 36°

2x = 2 x 36° = 72°

3x = 3 x 36° = 108°

∴ The two angles are 72° and 108°
