Question

hey plzz solve this ..​

Answer 1

Step-by-step explanation:

1) AB=13cm

AC=5cm

AB²=BC²+AC²

(13)²=BC²+(5)²

169=(BC)²+25

(BC)²= 169-25

(BC)²=144

BC=12cm

{Angal B=theata}

a)cos theata=BC/AB

=12/13 ans-

tan theata=AC/BC

=5/12 ans-

b)cot theata=BC/AC=12/5

sec theata=AB/BC=13/12

12/5-13/12=79/60 ans-

c)sin theata=AC/AB=5/13

2 sin theata-3 cos theata

2×5/13-3×12/13=-2 ans-

d)13×5/13-13×12/13=-7 ans-

i hope ! i have helped you.
