a. Stephan says that ΔXWV ≅ ΔUWS by the SAS congruence postulate. Do you Agree or Disagree? Justify your decision. Hint: State if you agree or disagree. - If you agree, identify the congruent corresponding parts that prove your opinion and the reason you know they are congruent. - If you disagree, identify the existing congruent corresponding parts and the part(s) that are needed but not provided to prove the triangles congruent using SAS.b. Suppose that it is also known that ∠V≅∠S.Which postulate or theorem can be used to prove that ΔXWV ≅ ΔUWS?Justify your decision.Hint: Provide the name of the congruence postulate or theorem. - Then, identify the existing congruent corresponding parts and the reason you know they are congruent. - However, if you think there is not enough information to prove the triangles congruent, identify the existing congruent corresponding parts and the part(s) that are needed but not provided.Please Help!!!

An object is launched directly in the air at a speed of 64 feet per second from a platform located 16 feet in the air. The motion of the object can be modeled using the function f(t)=−16t2+64t+16, where t is the time in seconds and f(t) is the height of the object. When, in seconds, will the object reach its maximum height? Do not include units in your answer.
