Question

If RV=w and SU=w–30, what is the value of w?

Answer 1

w = 60

Explanation:

the midsegment SU is half the measure of side RV , then

SU =
`(1)/(2)` RV , so

w - 30 =
`(1)/(2)` w ( multiply through by 2 to clear the fraction )

2w - 60 = w ( subtract w from both sides )

w - 60 = 0 ( add 60 to both sides )

w = 60
