Answer:
D Not enough information
Step-by-step explanation:
They give us one pair of congruent sides and we know there is a pair of congruent angles because of vertical angles however we can't say for sure that the sides are equal because there is no theorem to prove it and we can't guess by eye in Geometry
Hope This Helps :)
step by step explanation:
Add 1 to both sides
52x−1+1=12x+1
Simplify
52x=12x+1
Subtract 12x from both sides
52x−12x=12x+1−12x
Simplify
40x=1
Divide both sides by 40
40x40 =140
Simplify
x=140
Answer:
