Answer:
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!

If you see a negative number as a result from a ^2 you have to think it away first.
(4x+28)+(x+19)+(3x+13)=180
8x+60=180( combine like terms)
8x+60-60= 180-60
8x=120
8/8x=120/8
x=15
The missing angles are 88°, 34° and 58°
