Sum/Difference of 2 monomials is (in simplest terms) a monomial when the 2 monomials are 'like terms
Triangles equal 180 degrees total
It’s a right triangle so one of the angles is 90 degrees and we know another angle is 36.6
So 90+36.6= 126.6
180-126.6= 53.4
So I’m assuming the correct answer is C since that’s the closet number to 53.4
C. Above the dashed line.
It becomes:
y > 1/2x +3/2
