Question

I’m triangle DEF the measure of angle D is 36 and the measure of angle E is 92. Find the measure of angle F A.128 degrees B. 52 degrees C. 54 degrees D. 88 degrees

Answer 1

B

Explanation:

the sum of the 3 angles in a triangle = 180° , that is

∠ D + ∠ E + ∠ F = 180° ( substitute values for D and E )

36° + 92° + ∠ F = 180°

128° + ∠ F = 180° ( subtract 128° from both sides )

∠ F = 52°
