GUESS I NEED HELP PLEASEE!

x is 90°

Step-by-step explanation:

Get rid of the line that splits the 40° and 50° angle and it will equal 90°. The side opposite the 90° angle is also 90°. The whole angle, 90°+90°+x°+y° will add up to 360°. x° and y° are the same amount.

360°-90°-90°=x°+y°

360°-180°=x°+y°

180°=x°+y°

x° and y° are the same as I said earlier because they are opposite each other. So now x°+y°=180° which means x° and y° are both 90° each.
