Answer:

27 and 63

Explanation:

x - y = 36

x + y = 90

add the equations together

2x = 126

x = 63

substitute x for x in the first equation

63 - y = 36

y = 27

Answer:

27°,63°

Explanation:

Let the two angles be a and b.

They are complementary, meaning they add up to 90. Thus:


a+b=90

And we are told their difference is 36. Therefore:


a-b=36

Solve for the system of equations. Add b to both sides in the second equation:


a=b+36

Substitute this into the first:


(b+36)+b=90

Combine like terms;


2b+36=90

Subtract 36:


2b=54

Divide by 2:


b=27

So, b is 27 degrees.

Use the second equation again:


a-b=36

Now that we know b is 27, substitute:


a-27=36

Add 27 to both sides:


a=63

So, a is 63 degrees.

And we're done :)
