ANSWER
D) sin Y
EXPLANATION
The given triangle is a right triangle.
This implies that that:

Then we have

Recall that

But

When we do the substitution, we get,

Therefore cos(x) is a equivalent to sin(y).
The correct answer is D.

9514 1404 393
Answer:
Step-by-step explanation:
We can subtract the second equation from 4 times the first:
4(a +b) -(4a +1.5b) = 4(95) -(267.5)
2.5b = 112.5 . . . . . simplify
b = 45 . . . . . . . . . . divide by 2.5
a = 95 -b = 50 . . . find 'a'
The solution is (a, b) = (50, 45).

is it a triangle
Answer:
x = 10
y = 5
Step-by-step explanation:
Let the two numbers be x and y
Difference between the two is 10
x-y = 10
Sum;
x+ y is four times the smallest number
Let the smaller number be y
x+ y = 4y
Subtracting equation ii from i
-2y = 10 -4y
4y-2y = 10
2y = 10
y = 10/2
y = 5
Recall;
x-y = 10
x = 10 + y
x = 10 + 5 = 15
