Answer 2

PBP

--------- , sinA= P/H, cosA= B/H AND

HHB

tanA = P/B

cosA = 5/13 = B/H

it means

B=5, H= 13

by using pythagorous theorm

H²=P²+B²

P²= 13² - 5²

P² = 12²

P= 12

cosec A = 1/sinA

= H/P = 13/12

now,

cosecA/(cosA+cosecA)

= (13/12)/(5/13 + 13/12)

= (13/12)/ (60+169)/156

=

$\frac{13}{12} \times \frac{13 \times 12}{229} \\ \\ = \frac{169}{229}$
