10.
a) x- is the time after which the total cost is the same.
24 + 99x - is the cost in the dealership
45 + 89x is the cost at the local mechanic
24 +99x = 45 + 89x
99x - 89x = 45 - 24
10x = 21
x= 2.1 (hours)
b) 24 +99x < 45 + 89x
x< 2.1
The repairs cost less in dealership when work takes less than 2.1, and the dealership is better, because the cost of parts is less in the dealership.

This is the definition of Experimental probability
The answer is 30°.
Rule: All three sides must add up to 180°.
Since A=60 and the side vertical to the angle which is 90° then side C would be C=90° and that adds up to 150°, so you can conclude that angle B is 30°.
I hope I helped!
