X= -2 or X= 3 either one works.

Given,
Area = 225 yd²
Base = 30 yd
Height = [To be calculated]
To find:
The height of the given triangle.
We know that, area of a triangle is:

Therefore, the require height is 15 yd.
Proof:


The correct answer is b), the probability of B occurring given A has occurred.
Answer:4320cm
Step-by-step explanation:
(length of the arc)/(length of the radius)=central angle
lengthof the arc/20=216
lengthof the arc=216×20
length of the arc=4320cm
