Answer:
x = 4
Step-by-step explanation:
1. Find the degree measure of the unknown angle:
90-68 = 22 degrees
2. Find the appropriate slope ratio:
22 degrees = 2/5
3. Redraw the right triangle on a coordinate plane with the right angle on the origin if you have trouble visualizing the next step.
4. 2/5 = rise/run = x/10
2/5 = x/10
x = 4
-4x-2y = 16
2y = -4x-16
Get one variable alone on both equations
-4x - 16 = 2y
-4x - 16 = 2y
You'll realize that they're the same equation.
Use substitution
-4x-16 = -4x-16
0 = 0
x = all solutions
Use x = all solutions in an earlier equation to find y
-4x - 16 = 2y
SInce x can be all solutions y is also all solutions
y = all solutions
The answer for that equation would be 281
