Explanation:

Represent D and E as x because you don't know them

Now the sum of all these angles is 180

so,D+E+90(THE SIGN AT THE TOP)=180

D which is x the E which is also x

x+x+90=180

2x+90=180

2x=180-90

2x=90


(2x)/(2) = (90)/(2)

cancel and you will get x as 45

therefore x is 45 degrees
