In the diagram below of triangle UVWUVW, XX is a midpoint of \overline{UV} UV
and YY is a midpoint of \overline{VW}
VW
. If XY=54-6xXY=54−6x, and UW=73-7xUW=73−7x, what is the measure of UWUW?

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
