Answer:
27.7°
Step-by-step explanation:
To find m<A, apply trigonometric function.
Reference angle = A
Side length opposite to A = 20
Hypotenuse = 43
Apply SOH, which is:
Plug in the values
A ≈ 27.7° (nearest tenth)
Answer:
4/6
Step-by-step explanation:
→ Write the slope formula
(y₂ - y₁) ÷ (x₂ - x₁)
→ Substitute in the numbers
(3 - -1) ÷ (4 - -2)
→ Simplify
4/6
Hold on lemme do the work
Answer:
30000 feet
Step-by-step explanation:
temperature on ground level = 65 °F
temperature at cruising altitude = -43 °F
total decrease in temperature = 65 - (- 43) = 65 + 43 = 108 °F
for each 1000 feet elevation temperature drops by 3.6 °F
and we have the total drop of temperature as 108 °F.
so, Height of plane at cruising altitude = (drop in temperature/ 3.6) X 1000
=
= 30000 feet
