Find the measure of angle a

Step-by-step explanation:

Notice that angle A is identified with the algebraic expression "7 + 3 x", while the other acute angle is identified with the expression "5 x - 5"

We know that the third angle is a right angle (90 degrees),

and also that the sum of the internal angles in a triangle must give 180 degrees, so we have:

Now that we know x, we can give the answer for what angle A is:
