Question

Help ^^^ use picture above

Answer 1

The question reminds you of all the tools you need:

It says ...

"Opposite angles are equal."
So the upper right angle is x+40 just like the bottom left,
and the bottom right angle is 3x+20 just like the upper left.

And it says ...

"The sum of all angles is 360°."
You know what each of the four angles is, so you can addum all up,
set the sum equal to 360, find out what number ' x ' is, and then
use that to find the size of every angle.  

Answer 2

Solve for x in the equation 2(x+40)+2(3x+20)=360 and then plug x value back in for each angle, x=40 therefore, top angle=110 and bottom=70
