The 3 inside angles of a triangle need to = 180 degrees
you are given 70 and 80 which = 150 degrees ( 70 +80 = 150)
so the missing angle (PQR) = 180 - 150 = 30 degrees
Yo im sorry but I can’t help I’m jus trying to answer questions so I can ask them
<span>2y^2 + 12y- 54
=2(</span>y^2 + 6y- 27)<span>
=2 (y - 3)(y+9)</span>
Here's link to the answer:
