Answer:
see below
Step-by-step explanation:
5(4 + 8) =
Distribute
5*4 + 5*8
20 + 40
60
5*8+2
When a letter is next to a number u multiply
5*8+2=42
15x10=150
Subtract 5x5=25 small square cut out
150 -25= 125 sq ft
D
Answer:
52feet
Step-by-step explanation:
The set up will be a right angle
Let the angle of depression be 30°
The height above the sea level will be the opposite
The distance of the ship from the base is x (adjacent)
Using TOA
Tan theta = opposite/adjacent
Tan 30 = 30/x
x = 30/tan 30
x = 30/0.5774
x = 51.96
x ≈ 52 feet to the nearest foot
