Question

betermine the angles in the Mangle,912290x - 28

Answer 1

To solve fo x, equate all the angles to 180 degree

That is;

x + x - 5 + x - 28 = 180 (sum of angle in a triangle)

3x -33 = 180

Add 33 to both-side

3x =213

Divide both-side by 3

x = 71

The angles are;

x = 71°

x - 5 = 71 - 5 =66°

x - 28 = 71 - 28 =43°
