Find the trig ratio. Reduce to<br> lowest terms.<br> 10<br> 24<br> sin A =
Luba_88 [7]

The value of sin A is equal to \frac{5}{13}.

<h3>RIGHT TRIANGLE</h3>

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  In this triangle from the trigonometric ratios or the Pythagoras Theorem (hypotenuse^2=(side_1)^2+(side_2)^2), it is possible finding angles or sides.

<h3>Trigonometric Ratios</h3>

The main trigonometric ratios for a right triangle are presented below.

sin\alpha =\frac{opposite \; side}{hypotenuse}

cos\alpha =sin\alpha =\frac{adjacent\; side}{hypotenuse}

tan\alpha  =\frac{opposite \; side}{adjacent\; side}

The question asks the sin A. First, you should find the hypotenuse from Pythagoras Theorem.

hypotenuse^2=(10)^2+(24)^2\\ \\ hypotenuse^2=100+576\\\\ hypotenuse^2=676\\ \\ hypotenuse=26

Now you can find sin A.

sin\A=\frac{10}{26}=\frac{5}{13}
