Answer 1

Answer:

Let the angles be = x, 2x

3x+72=180(angle sum property)

= 3x= 180-72

= 3x= 108

= x= 36

Sides are = 36, 72

Answer 2

Answer:

36° and 72°

Explanation:

let the angles be 1x and 2x

so

1x +2x + 72=180. (angle sum property)

3x= 180-72

3x=108

X= 108/3

X= 36

therefore

1x. 2x

1×36. =2×36

=36°. =72°
