Question

In triangle EFG, m∠E = 87.4° and m∠F = 43.8°. Determine the measure of the exterior angle to ∠G.

131.2°
114.4°
48.8°
43.6°

Answer 1

Answer: 48.8

Explanation:

87.4+43.8+x=180

Step 1: Simplify both sides of the equation.

87.4+43.8+x=180

(x)+(87.4+43.8)=180(Combine Like Terms)

x+131.2=180

x+131.2=180

Step 2: Subtract 131.2 from both sides.

x+131.2−131.2=180−131.2

x=48.8

Answer 2

Answer is 48.8. 87.8+43.8=131.2 then 180- 131.2 =48.8
