Answer:
The answer is 10.
Step-by-step explanation:
Answer:
x = -62.5
Step-by-step explanation:
y = kx
-4 = k(25)
k = -4/25
y = (-4/25)x
10 = (-4/25)x
x = 10 × 25/-4
x = -62.5
In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:
sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse
