Answer:
A. 105°
Step-by-step explanation:
∠4 + ∠5 = 150
∠4 ≅ ∠5
150 ÷ 2 = 75
∠4 = 75
∠5 = 75
180 - 75 = 105
∠1 = 105
Answer:
x = 10°
y = 14
Step-by-step explanation:
Angle A = angle B = angle C = 6x ( equilateral triangle has equal angles )
therefore
Angle A + Angle B + angle C = 180° ( sum of angle in a triangle)
6x + 6x + 6x = 180
18x = 180°
divide both sides by 18
x = 10°
to get y
side AC = AB = BC ( equilateral triangle has equal sides )
