Answer:
2
Step-by-step explanation:
X would be 63, Y would be 27
A straight line is 180 degrees. 180-117=63
To find Y, since we know it is a 90 degree angle do 90-63 which is 27.
I believe the answer is B. -3.
Answer:
The acceleration is

Step-by-step explanation:
Use the equation of motion,

where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.
We substitute the values into the equation and solve for the acceleration, a

This means that;

Divide both sides by 2 to get:
