We can complete the square to rewrite 
as
Then solve for when 
:
D- none of the above
(y4)(y6)=24y
Answer:
C
Step-by-step explanation:
Sin represents opposite/hypotenuse. Thus, when A is the reference angle, 21 is the measure of the opposite side (CB) and 29 is the measure of the hypotenuse (AB).
Cos represents adjacent/hypotenuse. Therefore, when A is the reference angle, 20 is the measure of the adjacent side (AC) and 29 is the measure of the hypotenuse (AB).
