Answer: 
Step-by-step explanation:
You need to draw a right triangle as the one attached, where 
is the angle of elevation from the fire to the top of the fire tower.
You need to use the Inverse trigonometric function Arctangent:
Observe the triangle. You can identify that:
Then, you can substitute values:
Finally, evaluating, you get that the angle of elevation from the fire to the top of the fire tower is the following:
Rounded to the the nearest tenth of a degree:
Answer:
75% of 352 children are boys
Step-by-step explanation:
If 5/6 of the people participaticipants to a concert are adults then 1 out of 6 prople are children so we may reach a number of 2112:6=352 children
if 25% of the children are girls then 75% are boys
88×3=264 boys
Answer:
Step-by-step explanation:
30, the angle is worth 180 and 180-40=140. 140-20=120. 4*30=120
Looking at h and k values.
The vertex of a parabola ( h, k) is the point at which the parabola intersects the axis of symmetry.
Every parabola is symmetric about its axis, which means that if it were folded along its axis, the two parts would match. The fold or line that divides the parabola into two matching halves is called the axis of symmetry.
The axis of symmetry occurs at x = h.
