Question

Solve for x.
A) -7
C) 6
B) 9
D) 10

Answer 1

The answer for this is A -7

Answer 2

A

Explanation:

The segment BC joining the midpoints of 2 sides of the triangle is

Half the length of the third side, that is

x + 31 = 2(x + 19)

x + 31 = 2x + 38 ( subtract x from both sides )

31 = x + 38 ( subtract 38 from both sides )

- 7 = x → A
