A and B are complementary angles. If A = 4x + 6 and B = 4x - 4, then find the measure of A.

if the two angles are complementary, that means they must add up to 90 degrees.

so, following that, we can craft this equation:

4x + 6 + 4x - 4 = 90

8x + 2 = 90

8x = 88

x = 11

now to find the value of A, all we have to do is plug the value of x back into an original expression.

4(11) + 6 = 44 + 6 = 50 = A.

hope this helped! please let me know if you have any follow-up questions. :)
