Is x greater than, less than, or equal to 43° ?

x is equal to 43 degrees

Step-by-step explanation:

This is because the two angles shown are vertical angles. Vertical angles are always congruent.

A short proof of this claim is to let y be the angle to the right of angle x. Note how x+y = 180. Then note how y+43 = 180 as well. Since the two left hand sides are equal to 180, this must mean x+y = y+43. Subtract y from both sides and we end up with x = 43. The "43" can be any positive number you want, as long it's less than 180 of course, and the same idea applies.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
