To find the y-intercept, we set x=0 and solve for y.
Answer:
sin(x) = 5/13
cos(y) = 5/12
Therefore, sin(x) = cos(y)
Step-by-step explanation:
Trig ratios:
where 
is the angle, O is the measure of the side opposite the angle, A is the measure of the side adjacent to the angle and H is the hypotenuse, of a right triangle
We have been given the measures of the two legs, so we can find the measure of the hypotenuse by using Pythagoras' Theorem 
(where a and b are the legs and c is the hypotenuse of a right triangle)
Now we can use the trig ratios:
Therefore, sin(x) = cos(y)
The first expression 3^2 · 5 · 7 and the fourth expression 3^3 · 11 show a number as a product of prime numbers in exponential form.
3^2 · 5 · 7 shows 315 as a product of prime numbers 3, 5 and 7, that is 3 · 3 · 5 · 7
In 4^2 · 5 · 7, the number 4 is composite which can still be written as product 2 · 2
For the third one 3^3 · 8, the number 8 is composite which can still be written as product 2 · 2 · 2
The fourth expression 3^3 · 11 shows 99 as a product of prime numbers 3 and 11 which is 3 · 3 · 11
If a || b and e|| f
then
x + 1 = y
y + z = 180
z = x - 3
x = 91 and y = 92 and z = 88
answer is 92
