Answer:
The answer is B
Step-by-step explanation:
75 + x = 90
First, Virginia had to write an equation to solve for x.
75 - 75 + x = 90 - 75
Second, Virginia used the subtraction property of equality to isolate x.
x = 15
Third, "x = 15" was the answer Virginia got after subtracting 90 and 75.
75 + 15 = 90
Finally, she had to verify her answer
Answer:
5
Step-by-step explanation:
see explanation, use tangent property to solve question
This problem is better understood with a given figure. Assuming
that the flight is in a perfect northwest direction such that the angle is 45°,
therefore I believe I have the correct figure to simulate the situation (see
attached).
Now we are asked to find for the value of the hypotenuse
(flight speed) given the angle and the side opposite to the angle. In this
case, we use the sin function:
sin θ = opposite side / hypotenuse
sin 45 = 68 miles per hr / flight
flight = 68 miles per hr / sin 45
<span>flight = 96.17 miles per hr</span>
