Question

In right angled triangle ∆PQR, Q = 90, R = @ and if sin @=5/13 then find Cos @ and Tan@​

Answer 1

Step-by-step explanation:

base =√13^2-5^2=√169-25

=√144=12

cos@=12/13

tan@=5/12

Answer 2

Step-by-step explanation:

sin@= 5/13

so,

cos@= ✓1-sin²@

= ✓1 - 25/169

= ✓144/169

= 12/13

now,

Tan@= sin@/cos@

= 5/13 / 12/13

= 5/12
