26^2 - 22^2 = 192, take the sqrt of that C:
Answer:
x=8.48
Step-by-step explanation:
Sin 45 = x/12
x=12 x sin 45
x=12 x .7071
x=8.48
This is false because 
is an irrational number, despite being between 1 and 2.
Use alternate interior angles.
The angle to the left of x is 32
The angle to the right of x is 68
Since the three angles(32, x, and 68) form a straight line, they are supplementary.
32+x+68=180
100+x=180 x=80
