Tan(30°) = 17/x
x = 17/tan(30°) = 17√3
The hypotenuse of the smaller triangle is as you show, 34.
sin(45°) = 34/y
y = 34/sin(45°) = 34√2
x = 17√3
y = 34√2
Answer:
0.08
Step-by-step explanation:
If u do the math or put it in the calculator u should get 0.08
90 seconds = 1.5 minutes
1.5 minutes = 28 revolutions
Revolutions in 1 minute = 28/1.5 = 18.67 revolutions
Revolutions in 4 minutes = 18.67*4
= 74.7 (approx.) revolutions
The answer is 150in squared
Answer:Thus if b is the speed of the boat in still water, and c is the speed of the current, then its total speed is
Downstream speed = b + c
When a boat travels against the current, it travels upstream
