Answer:
x = 466.6 ft
y = 240.3 ft
Step-by-step explanation:
Cos(31) = 400 / x
So
x = 400 / Cos(31)
x = 400 / 0.8572
x = 466.6 ft
tan (31) = y / 400
y = 400 * tan(31)
y = 400 * 0.6009
y = 240.3 ft
We are asked to find 7 is what percent to 30.
We will use proportions to solve our given problem.
Let us assume that 7 is n% of 30. So we can set a proportion as:
Let us solve for n.
Therefore, 7 is 
of 30.
