Astone is dropped from the roof of a tall building. a person measures the speed of the stone to be 49 m/sec when it hits the ground. the height of the building is closest to:
select one:
a. 24 meters.
b. 49 meters.
c. 122 meters.
d. 245 meters.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
