If x represents the mesure of the small angle and
these two angles are complementary, find the
measure of each angle

I don't think that's enough information to solve the problem

Ok so,

Let's substitute the ? For y.

X + y= 90 degrees

Y= 2x-3

So x + 2x-3=90 using the substitution property.

Then you need to solve for x which leaves you with x=31.

But that's not the final step.

You're not solving for x you are solving for the y or in this case the ?.

After that you can either subtract 31 from 90 or multiply 31 times 2 and subtract three.

Either way you end up with 59.
