Answer:
x=5
Step-by-step explanation:
We simplify the equation to the form, which is simple to understand
3x+5-5=20-5
We move all terms containing x to the left and all other terms to the right.
+3x=+20-5-5+5
We simplify left and right side of the equation.
+3x=+15
We divide both sides of the equation by 3 to get x.
x=5
M <CAE = 360 - 240 = 120 degrees answer
(C) cause 17•3=51+39= 90 and that’s a 90 degree
