Which angles are supplementary to each other​

m = 12.728 or 18/root (2)/2, n = 9

Step-by-step explanation:

To find m, we can use sin(45) and cos(45).

Since sin(45) = root (2)/2  and this equals 9/m.

We set the equation root (2)/2  = 9/m and solve for m.

9 divided by root (2)/2 would give us 18/root (2), or 12.728.

m is 12.728.

Same process for n but we are using cosine this time.

cos(45) = root (2)/2 and this equals n/12.728.

Solving for n would give us root (2)/2 times 12.728.

This gives us that n is 9.
