(28 * x) -42 = 154
28x - 42 = 154
28x = 196
the unknown number is 7
There is no possible solution to y, we do not have an image or an equation that would allow us to solve the value of y, therefore our answer is 34y + 16y=50y
S = (n-2) x 180 to find the total angles.
5-2*180
3*180
540
540-86-140-138-59=117
Answer:
10
Step-by-step explanation:
4x+8+3x+12=90
