A softball is thrown into the air with an initial velocity of 5 meters per second from a height of 9 meters. The function below models the distance of the softball from the ground in meters after t seconds.
How many seconds does it take for the softball to hit the ground?

h(t)=4.9t^2+5t+9

your answer is a

so then what are you asking?

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
