Find the RATIO and the EXACT VALUE of the given CscB.​

Step-by-step explanation:

take angle B as reference angle

using cosec rule

cosec B=hypotenuse/opposite

cosec B=13/12

cosec B=1.08

B=cosec 67

B=67 degree

for ratio,

cosec B=13/12

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
