Answer 2

Answer:

(A) 23/8

Step-by-step explanation:

sinA = 8/17

P = 8

H = 17

ATQ

P²+B² = H²

8²+B² = 17²

B² = 17² -8²

B²=(17+8)(17-8)

B²=225

B=15

cosA=B/H=15/17

secA = 1/cosA

cosecA= 1/sinA

secAcosA=cosecAcosA

(1/cosA)(cosA) +(1/sinA)(cosA)

1 +cosA/sinA

1+cotA (cotA=cosA/dinA)

1+15/8

8+15/8

23/8
