pls help!I have trouble with this but ik everything is supposed to add up to 360 degrees

Because each of these angles are 90 degrees, we know they're each equal to each other.
Let's find the value of the variable y first.
We can use 5y - 17 = 2y + 50 to find the value of y.
5y - 17 = 2y + 50
-2y from both sides
3y - 17 = 50
+17 to both sides
3y = 67
Divide both sides by 3
y = 22.33
Now we need to find the value of x.
x + 44 = 7x - 248
-x from both sides
44 = 6x - 248
+248 to both sides
292 = 6x
Divide both sides by 6
x = 48.67
And there's your variables.
y = 22.33
x = 48.67
