Answer:
45 degrees
Step-by-step explanation:
42 degrees is 42 “points” away from zero (picture a number line). -3 degrees is 3 points away from zero on the number line, but in the opposite direction. The two numbers are 45 “points” away from each other.
When they say find the difference, it’s a subtraction equation.
42 - (-3) = 42 + 3 = 45
