Question

What is the value of x?
A)4
B)2
C)5
D)3

Answer 1

D

Explanation:

given the base angles∠ B = ∠ C , then Δ ABC is isosceles with the two legs being congruent ( equal ) , that is

AB = AC ( substitute values )

6x - 3 = 3x + 6 ( subtract 3x from both sides )

3x - 3 = 6 ( add 3 to both sides )

3x = 9 ( divide both sides by 3 )

x = 3
