Triangle vwt is an isosceles. which equation can be used to find the measure of∠v?
a) 2x = 52
b) x + x – 52 = 180
c) 180 + 52 = x + x
d) 180 = 2x + 52

  D)

Step-by-step explanation:

Given :  Triangle VWT is an isosceles.

We know that an isosceles triangle has two sides and angles equal.

From the given picture , it is clear that  [∵ Angles opposite to equal sides of a triangle are equal].

Also, the sum of interior angle of a triangle is 180°.

So for ΔVWT , we have

Hence, the equation can be used to find the measure of∠V is .

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
