Question

…. I need help again oof

Answer 1

m∠WVZ=90°

m∠XVW=90°

Explanation:

m∠WVY=m∠WVZ+m∠ZVY

180°=9x-15°+90°

180°=9x+75°

180-75=9x

105°=9x

⇒x =
`(35)/(3)`

So. m∠WVZ is

`=9((35)/(3))-15=3*35-15\\=105-15=90`

m∠WVZ=90°

and same will be the m∠XVW

m∠XVZ=m∠XVW+m∠WVZ

180°=m∠XVW+90°

m∠XVW=180°-90°

m∠XVW=90°
