False. Lines that intersect at a 90-degree angle are perpendicular.

I hope this helps!

Angle A abd B are complementary find angle A and B

scZoUnD [109]

m∠A + m∠B = 90, since the angles are complementary.

The question also tells us that m∠A = (2x + 10) and m∠B = (-x + 55)

So, all we have to do is input the angle's values into the first equation:

(2x+10) + (-x+55) = 90

Simplify:

x + 65 = 90

x = 25

Input the variable into the angles:

m∠A = 2(25) + 10 = 50 + 10 = 60°

m∠B = -25 + 55 = 30°
