Chapter E, Problem 8.7EX

To determine

To find the value of $\sin T$ .

Answer to Problem 8.7EX

Option (c)

Explanation of Solution

Given information: A right angled triangle $\Delta RST$ with $\angle S=90°$

Concept used:

In right angles triangle,

$\sin \theta$	$\cos \theta$	$\tan \theta$
P	B	P
H	H	B

Where, P, B and H be the perpendicular, base and hypotenuse of right angled triangle.

By Pythagoras theorem, $B^2+P^2=H^2$

  $\sin T=\frac{RS}{RT}$
