Question

sin a =4\3 then find then find the other values of angle A​

Answer 1

Answer:

Sin A=4/3

BC/AB=4/3

SO,AB=3

BC=4

AC=?

Using phythagoras theorem

(H)²=(P)^2+(B)²

(3)²=(4)²+(B)²

9=16+(B)²

(B)²=16-9

(B)²=7

B=√7

so,AC=√7

CosA=B/H

CosA=√7/3

TanA=P/B

TanA= 4/√7

Cosec A=H/P

Cosec A= 3/4

Sec A= B/H

Sec A= √7/3

Cot A= B/P

Cot A= √7/4
