Where’s your z? incomplete question
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)
Answer:
3 3/5
Step-by-step explanation:
it is right because equivalent fractions are different fractions that name the same number. i think this is right. i hope so. good luck
Answer: Find the tax on an income on 77,911 and subtract 19,458, then divide it by 679.34
To find this answer, you first need to find the tax on an income of 77,911, you should have a table or equation for that. Then, subtract the amount of tax withheld (19458). This will give you the refund. Divide that by the amount of your payment and you will have your answer.
12.5
12=96x/100
x=(100*12)/96
x=1200/96
x=12.5
