Answer:
7/10
Step-by-step explanation:
first you find a common denominator which would be 10 so you turn 1/5 into 2/10 and 1/2 into 5/10 and then add 2/10 + 5/10 =7/10
Angles on a straight line add up to 180 degrees so
45 + 3x = 180
Subtract 45 from both sides to remove the 45 on the left
3x = 135
Then divide both sides by 3
x = 45
Answer is X = 45
