Need the answer to number 4

/2

Step-by-step explanation:

lets find hypotenuse( longest side) first

let other two samller sides be a and b and hypotenuse be c

pythagorsd theorem

a^2 + b^2 =c^2

9^2 + 2^2 =c^2

81 + 4=c^2

85 =c^2

=c

take theta as reference angle

cosec theta=hypotenuse/opposite

= / 2

answer:

c 60% on edg
