Answer:

x = 6

Step-by-step explanation:

The midsegment is half the measure of the parallel side 36, thus

3x = 18 ( divide both sides by 3 )

x = 6

If PQR ~ UTV, find the value of x.

user100 [1]

The value of x is 15.

Solution:

Given ΔPQR $\sim$ ΔUTV.

<em>If two triangles are similar, then the corresponding parts are congruent.</em>

$$\Rightarrow \frac{PR}{UV} =\frac{RQ}{VT}$

$$\Rightarrow \frac{14}{x + 6} =\frac{8}{x -3}$

Do cross multiplication, we get

⇒ 14(x - 3) = 8(x + 6)

⇒ 14x - 42 = 8x + 48

Add 42 on both sides.

⇒ 14x = 8x + 90

Subtract 8x on both sides.

⇒ 6x = 90

Divide by 6 on both sides.

⇒ x = 15

The value of x is 15.
