the first blank is 82, the second blank is 8,910. I got that third blank wrong and it should be 7.1 I think. and the last block is should not. to find the third box all you need to do is:
82+990=1,072 then divide 82 by 1,072 and round to the nearest tenth

A zip line is setup 150ft in the air, where a person can expect to zip line at a safe declining speed to the ground as they pass

hichkok12 [17]

Answer:

139 ft

Step-by-step explanation:

So the zip line forms a right triangle. The height of the triangle is 150 ft, and the opposite angle is 40°. The horizontal distance covered by the zip liner can be found with trigonometry, specifically with tangent.

tan 40° = 150 / x

x = 150 / tan 40°

x ≈ 179 feet

But this includes the 40 ft long body of water, so the amount of ground covered is:

179 ft - 40 ft = 139 ft
