A hot air balloon is 2,750 feet above the ground. The angle of depression from the basket of the balloon to the base of the silo
is 42 degrees. Set up, but DO NOT solve an equation that would be used to find the distance from the basket to the base of the silo. **Must provide an explanation to go with your equation. Do not solve your equation!

Answer:
d = 2750 ÷ sin 42°
d = [2750/(sin 42°)]
We're told not to solve the equation.
Step-by-step explanation:
From the attached image
The angle of elevation of the basket from the base of the silo = the angle of depression of the base of the silo from the basket of the hot air ballon = 42° (alternate angles are equal)
So, from here, trigonometric relations can then be used to calculate the distance from the basket to the base of the silo
Sin θ = (Opp/Hyp)
θ = 42°, Opp = 2750 ft, Hyp = d
Sin 42° = (2750/d)
d = 2750 ÷ sin 42°
d = [2750/(sin 42°)]
Hope this Helps!!!

Profit percentage for weaver after selling mat is equals to 140%.
<h3>What is percentage ?</h3>" Percentage is defined as the hundredth part of the whole given quantity. It is represented by symbol %."
Formula used
Profit% = × 100
According to the question,
Given,
Cost price of bundle of grass = $50.00
Number of mats made = 8
Selling price of each mat = $15.00
Therefore,
Selling price of 8 mats = 15 × 8
= $120
Selling price > Cost price
Therefore,
Profit = Selling price - Cost price
= 120 - 50
= $70
Substitute the value in the formula to get profit percentage we get,
Profit% = ×100
= 140%
Hence, profit percentage for weaver after selling mat is equals to 140%.
