Answer:
4.02°
Step-by-step explanation:
The angle of descent can be obtained using trigonometry ;
Since we have a right angled triangle ;
Let's use the relation:
Sin θ = opposite / hypotenus
Hypotenus = 2.7 miles
1 mile = 5280 feets
2.7 miles = (2.7 * 5280) = 14256 feets
Sin θ = 1000 / 14256
Sin θ = 0.0701459
θ = sin^-1(0.0701459)
θ = 4.0223674
Answer:
376 inches^2
Step-by-step explanation:
<h3>1. Divide up each type of rectangle </h3>
- 10x6
- 6x8
- 8x10
<h3>2. Find the area of each rectangle</h3>
- 10x6=60
- 6x8=48
- 8x10=80
<h3>3. Multiply each rectangle by two to get the opposite one</h3>
- 60x2=120
- 48x2=96
- 80x2=160
<h3>4. Add them together</h3>
120+96+160=376
The surface area is 376 inches^2
