Answer:

Trigonometric ratio is the special measurements of a right triangle. There are three basic trigonometric ratios which are sine , cosine , and tangent.

Step-by-step explanation:

What is sine? The sine of an angle x is the length of the opposite side.

What is cosine? The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.

What is tangent? The tangent of an angle is the length of the opposite side

Tangent and sine are very closely related and easily mixed up. Be carful with your calculations for the most accurate answer.

Can someone tell me why the answer is 2?

Ira Lisetskai [31]

Answer:

If we put x=2 in the given equation, we get the answer for the equation as 2

Given:

$\sqrt{-3 x+10}=x$

To find:

Why the answer is 2

Solution:

If we substitute the value x=2 in the given option, we get

$\sqrt{-3(2)+10}=2$

$\sqrt{-6+10}=2$

$\sqrt{4}=2$

Result:

Thus we can say that when substitute the value of x=2

We get the answer as $\sqrt{-3 x+10}=2$

A circle has a diameter of 14cm Work out the circumference of this circle. Give your answer in terms of 3.14 and state it's unit

Karolina [17]

C = 14π cm ( in terms of π )

the circumference (C) of a circle is calculated using the formula

C = πd ( where d is the diameter )

C = 14π cm ≈ 3.14 × 14 - 43.96 cm

Solve the equation square root of x plus three plus four equals five for the variable. Show each step of your solution process

alekssr [168]

Answer:

$x=-2$

Step-by-step explanation:

The given expression is

$\sqrt{x+3}+4=5$

We group the constant terms on the right hand side to obtain;

$\sqrt{x+3}=5-4$

$\Rightarrow \sqrt{x+3}=1$

We square both sides of the equation to remove the square root.

$\Rightarrow (\sqrt{x+3})^2=1^2$

$x+3=1$

This will simplify to;

$x=1-3$

$x=-2$
