Answer:
B
Step-by-step explanation:
120+4x-12=180, 4x+108=180,4x=72, x=18
The first one because it’s the actual formula for a sphere and it has pie at the end because we are solving for a sphere
164+56−(3+4+1)
=220−(3+4+1)
=220−(7+1)
=220−8
=212
theta is in the fourth quadrant where the cosine is positive.
the third side in the triangle = sqrt (4 - 2) = sqrt2
So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)
tan theta = - sqrt2 / sqrt2 = -1
