Question

Find sin(b) in the triangle. A.4/3 B.3/5 C.3/4 D.4/5

Answer 1

The value of $\sin \beta$ in the given triangle ABC is $\dfrac{4}{5}$. Option D is correct.

What are the trigonometric ratios?

Trigonometric ratios are the ratio of sides of a right angled triangle. There are 6 types of trigonometric ratios: sin, cos, tan, cosec, sec, and cot.

Sine trigonometric ratio is the ratio of perpendicular (side opposite to the angle) to the hypotenuse.

In the given figure, the side opposite to the angle $\beta$ is AC = 4 and the hypotenuse is AB = 5.

So, the sine ratio will be equal to,

$\sin \beta=\dfrac{4}{5}$

Therefore, the value of $\sin \beta$ in the given triangle ABC is $\dfrac{4}{5}$. Option D is correct.
