Question

if sec tita 13/5 then sin tita =​

Answer 1

Answer:

Sin theta=12/13

Step-by-step explanation:

Sec theta=13/5 i. e.. Hypotenuse/adjacent.

Then other side of triangle=12 (using Pythagoras theorem of right angled triangle)

Therefore, sin theta =opposite/hypotenuse

=12/13.

Answer 2

Answer:

if sec theta is 13/5 then sin theta will be 12/13

Step-by-step explanation:

sec theta =13/5

there is a right triangle named ABC and if we let a=theta

then sec theta =hypotenuse /base

so we will apply pythagoreas theorum;

(AC)²=AB²+BC²

SO 13²=AB²+5²

so 169=AB²+25

169-25=AB²

AB=12 cm.

now

hypotenuse is 13 cm

base is 5 cm

and perpendicular is 12 cm

so we have to find sin theta

sin theta is perpendicular/hypotenuse

so answer is 12/13
