Answer:
A
Step-by-step explanation:
A. X=-3(4-1)
Answer:
7
Step-by-step explanation:
We have that
(v+6)^2 = 324-----> I raise to 1/2 both members----> [(v+6)^2]^(1/2)=(324)^(1/2)[(v+6)]=(324)^(1/2)-------------> v+6=√324
v=√324-6---------> 18-6=12
v=12
the answer is v=12
We know the cofunction identity

.
Thus, the tangent of 90° minus <span>θ also equals
