Answer:
x=40 degrees
Step-by-step explanation:
3x=120 (vertical angles)
solve: 3x=120
x=40
2 3/8 - 1/4 = 2 1/8 x 1/8 = 17/64.
To do this, you first need to do the problem in the (). You have to turn 1/4 with a denominator of eight, so the fraction becomes 2/8. 2 3/8 - 2/8 = 2 1/8. Now we have to turn 2 1/8 into an improper fraction by doing whole number x denominator + numerator. 17/8 x 1/8 = 17/64.
