Question

Solve for x, find the measure of all angles plzzzzz!! ​

Answer 1

∠ H = 22.5°, ∠ I = 45° , ∡ J = 112.5°

Explanation:

The 3 angles in a triangle sum to 180° , then

x + 2x + 5x = 180 , that is

8x = 180 ( divide both sides by 8 )

x = 22.5

Then

∠ H = x = 22.5°

∠ I = 2x = 2 × 22.5° = 45°

∠ J = 5x = 5 × 22.5° = 112.5°
