Answer:
53.1°
Step-by-step explanation:
Let x represent the wangle of elevation from B to C
Reference angle = x
Opposite side to x = 16 - 4 = 12
Adjacent = 9
Apply trigonometric ratio to find x.
Thus:


(nearest tenth)
Angle of elevation from B to C = 53.1°
Answer:
1xy
Step-by-step explanation:
30xy-28xy=2xy-xy=xy or 1xy
Answer:
I think is A
Step-by-step explanation:
-7x -13 ≥ 8
+13 +13
-7x ≥ 21 (then, divide by -7 and when u divide by a negative number, the sign flip)
Answer: x ≤ -3
Well on 3 for the circle its 1/2×15×8=60
