Question

Find the length of VZ

A. 30
B. 42
C. 10
D. 60

Answer 1

B

Step-by-step explanation:

First find the value of X. So since V is the midpoint, the equation would be

3x=2x+10

Subtract 2x from both sides and you get

x=10

Now substitute X with its value

5(10)-8=42

Hence B is the answer

Answer 2

Assuming this is a parallelogram where the diagonal bisect eachother:

set 2x+10=3x because the other diagonal splits this one into 2 equal (congruent) parts

Solve for x and get 10

Plug in 10 for 5x-8 and get 42
