Question

Find the value of x in the diagram given that AABC = ADEF.

(2x + 3)
X=
B
(6x-9)
E

Answer 1

x = 3

Explanation:

The sides are corresponding sides of a congruent triangles. This means that the sides equal each other.

2x + 3 = 6x -9 Subtract 2 x from both sides

3 = 4x + 9 Add 9 to both sides

12 = 4x Divide both sides by 4

3 = x
