Answer 1

∠ F = ∠ G = 40° , ∠ H = 100°

Explanation:

sum the parts of the ratio, 4 + 4 + 10 = 18 parts

Divide 180° ( sum of angles in triangle ) by 18 to find the value of one part of the ratio.

180° ÷ 18 = 10° ← value of 1 part of the ratio , then

∠ F = 4 × 10° = 40°

∠ G = 4 × 10° = 40°

∠ H = 10 × 10° = 100°
