Answer: Z> -17
z/2+26=17.5
We move all terms containing z to the left and all other terms to the right.
+ 0.5z=+17.5-26
We simplify left and right side of the equation.
+ 0.5z=-8.5
We divide both sides of the equation by 0.5 to get z.
z=-17
Two angles are 67.5 degrees and the 3rd angle is 45 degrees.
Formula: 2x + 45 = 180
Step-by-step explanation:
3х + 2y = 14
3х - 2y = 10
6x=24
x=4
3×4+2y=14
12+2y=14
2y=14-12
2y=2
y=1
