Acar increases, then decreases, its speed. which table could represent the speed of the car?

The second table.

The speed increases (45—>47—>49) then decreases (48—>47) over time.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

true
