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:
d = 3/4
Step-by-step explanation:
2.5 - d = 1.75
-2.5 -2.5
------------------
-d = -0.75
d = 0.75
d = 3/4
Yes because they both give you an x =2 and a y=-4
