Question

What is the value of x in the figure? Enter your answer in the box.

Answer 1

Explanation:

hi,

Opposite angle theorem:

• ∡a₁ = ∡a₂
• ∡b₁ = ∡b₂

__________

According to the theorem:

∡b₁ = ∡b₂ ⇒ 145° = ( 2x + 15 )°

145° - 15° = ( 2x )°

130° = ( 2x )°

x = 60°

Answer 2

x=65

Explanation:

145=(2x+15)(voa)

145-15=2x
130=2x

130/2=x

65=x
