Question

pls find WV
a.7
b.23
c.84
d.145

Answer 1

Answer:

$\mathrm{B}$

Step-by-step explanation:

$WV=XY$

$12x-61=3x+2$

$12x-3x=2+61$

$9x=63$

$9x/9=63/9$

$x=7$

$12x-61$

$12(7)-61$

$=23$

Answer 2

Answer:

B. 23

Step-by-step explanation:

This is a congruent triangle by SAS Postulate

So,

XY = WV

=> 3x+2 = 12x-61

=> 2+61 = 12x-3x

=> 63 = 9x

Dividing both sides by 9

=> x = 7

Now Side WV:

=> 12(7)-61

=> 84-61

=> 23
