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.

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

Set up a linear equation(s) that will help you to find a solution to the following problem: One angle of a triangle is twice as large as another angle. The measure of the third angle is 20 more than the measure of the smallest angle. Find the measure of each angle of the triangle.

remember
all angles add to 180

x+y+z=180
one is 2 times as another
x=2y
measure of 3rd angle (z) is 20 more than smalllest
since y has to be doubled to get x, y is smallest
z is 20 more than y
z=20+y

we have
x=2y
z=20+y
sub those
x+y+z=180
2y+y+20+y=180
4y+20=180
minus 20 both sides
4y=160
divide 4
y=40
sub back
x=2y
x=2(40)
x=80
z=20+y
z=20+40
z=60

the angles are
80 degrees, 40 degrees, 60 degrees

If y = x^3 - 1, find the value of y when x = 2.
