Answer:
36.9 degrees
Step-by-step explanation:
Calcolate the sine of the angle BAC by dividing the opposite cathetus by the hypthenuse. That gives us 3/5 = 0.6. Now use the calculator to calculate the amplitude of the amgle by using the sin^-1 (or arcsin) function, so write sin^-1(0.6)=36.9.
Answer:
nothing is seen
Step-by-step explanation:
I believe that the answer is C sorry if it is wrong.
To answer this item, we let x be the time for the faster plane and h be the distance traveled which is the same for both planes. Distance is calculated by multiplying speed and time. Thus,
(558)(x) = (496)(x + 0.5)
The value of x from the equation is 4.
