Answer:
Y = 10; X = 20
Step-by-step explanation:
In Question 22, the 2 angles in blue are supplementary (same side interior angles), meaning that the 2 angles sum up to 180 degrees, so setting up an equation to solve for y:
120 + 6y = 180 (subtract both sides by 120)
6y = 60 (divide both sides by 6)
y = 10
Same with Question 23:
45 + 5x + 35 = 180 (combine like terms)
5x + 80 = 180 (subtract 80 from both sides)
5x = 100 (divide both sides by 5)
x = 20
