Triangle PQR has vertices , , and . It is translated according to the rule

Given f(t) = 282 - 53 +1, determine the function value f(2). do not include f(z) = in your answer

1) in triangle the, what is the measure of angle t (in degrees)? 2) in triangle bat, the measure of angle b is 66∘, and the measure of angle t is 77∘.what is the measure of the exterior angle at a (in degrees)?

I'm confused on this could anyone me and show me what i need to do to solve it.
