Step-by-step explanation:
first fill out all sides of the triangle (use pythagorean theorem).
9^2 = 4^2+x^2
x^2 = 81-8 --> x^2 = 73 --> x = √73
csc theta --> hyp/opp
sin theta --> opp/hyp
cot theta --> adj/opp
hyp = 9, adj = 4, opp = √73
csc = 9/√73 --> 9√73/73
sin = √73/9
cot = 4/√73
Answer: angle 7 = 80 degree and angle 8 = 100 degree
