Answer:
10 x 2! x 2! x 2! x 2! = 10 x 16 = 160 ways.
Step-by-step explanation:
Ok so 2(x+1) would be two times the sum of a number and one. “Sum of a number and one” is just “x+1” and then it’s two times that because the two is outside of the parentheses.

Answer:
Angle 1 = 90 degrees
Angle 2 = 50 + 40, x = 50
