Question

Look at the triangle:

Answer 1

O A O
S H C H T A

Looking for s (sin)
O
So you use the triangle of S H

O = opposite
H = hypotenuse

So you’d then do the O/H
So the opposite being 12cm and the hypotenuse being 13cm

The answer would then be 13/12
Hope this helps! :)

Answer 2

Answer:

sinx°=12÷13

Step-by-step explanation:

We are given a right angle triangle with hypotenuse equal to 13 centimeters.

An acute angle of the triangle is labeled as x degrees.

The side adjacent to the acute angle has length 5 centimeters and the side opposite to the acute angle has length 12 centimeters.

Then the value of sin x°=Perpendicular/hypotenuse

(Perpendicular i.e. side opposite to angle x)

                                      = 12÷13
