These are problems like your answer to one problem = the number in the side of the thing

combining like terms in a polynomial is adding or subtracting together terms that have the same degree in the exponents.
example. 3x^3 + 5x^6 + 2x^3 +7x + 9x^6
= 7x + 5x^3 + 14x^6
Hi!
So the angles make a right angle which is also known as a complementary angle.
What you want to do is set both terms equal to 90
11x + 4x = 90
15x = 90
divide by 15
x = 6
now multiply 6 by 4 because you want to know whata angle 3 is
6*4 = 24
24 degrees is your answer!
Hope this helps!
