Answer:
23°
Step-by-step explanation:
Step 1:
< GEC + < ECG + < CGE = Δ ECG Sum of a Δ
Step 2:
< IGF = < GCE Corresponding ∠ 's
Step 3:
14° + 180° - 4x + 78° = 180° Substitution
Step 4:
272° - 4x = 180° Add / Algebra
Step 5:
- 4x = - 92 Subtract 272° on both sides
Step 6:
- 92 ÷ - 4 Divide
Answer:
x = 23°
Hope This Helps :)
Answer:
x = 23
Step-by-step explanation:
<IGF and <ICE are congruent because they are corresponding angles of parallel lines cut by a transversal.
m<ICE = m<IGF = 14
<BEC is an exterior angle.
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
m<BEC = m<EGC + m<ICE
4x = 78 + 14
4x = 92
x = 23
