Answer:
Step-by-step explanation:
5y and 45 are supplementary. They add to 180 degrees.
5y + 45 = 180 Subtract 45 from both sides.
-45 -45
5y = 135 Divide by 5
/5 /5
y = 27
2x+ 1 and 45 are vertically opposite which means they are equal.
2x+1 = 45 Subtract 1 from both sides
2x + 1 -1 = 45-1
2x = 44 Divide by 2
/2 /2
x = 22
