Hi there!

Since x is 10, we can just plug it into the equation.

= 7*10 + 10
= 70 + 10
= 80

So, the answer is 80.

Hope this helps!

9. You are standing on a mountain that is 6842 feet high. You are looking down at your campsite, creating an angle of depression

Mkey [24]

Answer:

Step-by-step explanation:

See the attached figure which represents the question.

Let the distance between campsite and the base of the mountain = d

The total height = 6842 + 5.6 = 6,847.6 feet.

As shown at the graph, the angle x and the depression angle are alternate angles, so they are congruent.

∴∠x = 38°

tan x = opposite/adjacent = (total height)/d = 6847.6/d

So, d = 6847.6/tan x

= 6847.6/tan 38° = 8,764.53 feet (to the nearest hundredth)

so, the distance between campsite and the base of the mountain = 8,764.53 feet
