Answer:
B
Step-by-step explanation:
Answer:
51
Step-by-step explanation:
tan(z) = 10/8
z = (tan^-1)(1.25)
z = 51.3401917459
What do you need to solve for?
X=r-4/7-s
S=-r/x+4/x+7
R=-sx+7x+4
The first thing we must do for this case is to look for the area of each rectangle.
We have then:
A1 = (40) * (x)
A2 = (1.25 * 40) * (y)
Then, we have the following relationship between areas:
"the area of Q is 10% less than the area of p"
A2 = 0.9 * A1
Substituting values we have:
(1.25 * 40) * (y) = 0.9 * ((40) * (x))
We rewrite:
50y = 36x
The relationship x: y is:
x / y = (50) / (36)
Simplifying:
x / y = (25) / (18)
Answer:
the ratio of x:y is:
25:18
