Question

of the following is correctly set up to solve for xx from the image abovelook at photo A-4x+2 = 3x+3 + 90. B-4x+2= 3x +3. C- (4x+2)+(3x+3) = 180. D-(4x+2)+(3x+3)=90.

Answer 1

we have the following:

angles supplementary add 180°, therefore:

$\mleft(4x+2\mright)+\mleft(3x+3\mright)=180$

The answer is C. (4x+2)+(3x+3) = 180
