Answer:
C and G
Step-by-step explanation:
(x^2+4)^2+32=12x^2+48 is written as 
.
We can simplify the expression using the term a by replacing x^2 + 4 with a.
This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.
a-4 = 0 a=4
a-8=0 a=8
Answer:
25.8 ft
Step-by-step explanation:
Draw a right triangle with the right angle at the foot of the tower. The interior angle of the triangle at the top is the complement of the angle of depression. 90 - 74 = 16; it measures 16°. The leg at the bottom has length x. The height of the tower is the vertical leg and is 90 ft. We are looking for x.
For the 16° angle, x is the opposite leg, and 90 ft is the adjacent leg.
tan A = opp/adj
tan 16° = x/(90 ft)
x = 90 ft * tan 16°
x = 25.8 ft
