Question

Given sin teeta = 12/13
calculate Costeeta and tanteeta
​

Answer 1

Answer:

Here Cosec teta is 13/12

Tan teta is 13/12× cos teta

Answer 2

Answer:

Step-by-step explanation:

Sin theta= P/H

12/13= P/H

So Perpendicular= 12 cm, Hypotenuse= 13 cm.

By Pythagoras Theorem calculate base:

Base= √(13)²-(12)²

=√25

= 5 cm.

(i) Cos theta= B/H

= 5/13

(ii) Tan theta= P/B

= 12/5

Here, P means Perpendicular, B means Base, H means Hypotenuse.

No need to convert fractions into decimal.

Hope it helps.!!
