User: what is the measure of the two angles (5x+7) + (3x+11)=90?

Weegy: (5x + 3)(3x + 1);

15x^2 + 9x + 5x + 3

= 15x^2 + 14x + 3

User: which of the following statements is true?

(5x+7) + (3x+11)=90
5x + 7 + 3x + 11 = 90
8x + 18 = 90
8x = 90 - 18 = 72
x = 72/8 = 9
5(9) + 7 = 52
3(9) + 11 = 38
The two angles are 52 degrees and 38 degrees.
