Explain how you would prove angle p is congruent to angle q. i need on number 12 asap!

How do i work this problem out using the equation a=pe^rt

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?
