Find sin(b) in the triangle.<br> A.4/3<br> B.3/5<br> C.3/4<br> D.4/5
DerKrebs [107]

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

<h3>What are the trigonometric ratios?</h3>

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.

Here is a right cone:
11111nata11111 [884]

Answer:

Choice B: A triangle

Choice C : A shape with two edges, one straight and one curved

Step-by-step explanation:

When a cone is cut by a plane that runs exactly through its vertex, and perpendicular to its base, the shape that is obtained is an isosceles triangle, when the section is viewed.

When a cone is cut through a plane that runs perpendicularly to its base, but not through its vertex, we can get two different shapes which have parabolas or hyperbolas as their curved edge, and a straight edge which is formed from the base of the cone

Step-by-step explanation:

A binomial experiment consist of n trials but for every trial there are only two possible outcomes.

1. A survey asking 75 people to name their favorite color

There can be more than two answers to the given question so it is not a binomial experiment.

2. A survey asking 75 people to give their age

The age can be any integer which makes the outcomes more than two so this is also not a binomial experiment.

3. A survey asking 75 people whom they voted for in the election

This is also not a binomial experiment as there can be more than two answers to the question

4. A survey asking 75 people if they like the new school building

The given question can only be answered in yes or no which means only two possible outcomes so this is a binomial experiment ..
