But do we know what the angles of a square are?

i dont think so all they gave me was what is in the screen shot

anonymous · Answer

I know... but you have to know a little more than what is given to solve it.
Angle A is 5x + 50. What is the degree of a right angle?

What is the angle of a flat line?
You must have learned this already if you are being asked questions like this...

anonymous · Answer

180

anonymous · Answer

wait the angle of the question u asked before is 90?

anonymous · Answer

Yes. A right angle has the degree measurement of 90.
Knowing that all angles are the same in a square, that means that <A, <B, <C and <D are the same.

If <A = 5x + 50, and <A is 90, then we have a new equation.

90 = 5x + 50
