What steps would I take to solve this question?

In triangle opq right angled at p op=7cm, oq-pq=1 determine the values of sinq and cosq

Lydia collected two sets of data one set of data shows an outlier. which set has an outlier, and which number is the outlier?

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)?
