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.

Answer:

y=-3x+4

Step-by-step explanation:

im assuming that you need the equation of the table

to find slope, y2-y1/x2-x1 10-4/-2-0

6/-2=-3 slope=-3

y=mx+b just sub in the numbers from a point in the table

10=-3(-2)+b

10=6+b

b=4

y=-3x+b

Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm. What is Rich's percent error in this c

Hitman42 [59]

Answer:

0.9%

Step-by-step explanation:

We have been given that Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm.

We will use percentage error formula to solve our given problem.

$\text{Percentage error}=\frac{\text{Experimental value-Actual value }}{\text{Actual actual}}\times 100$

$\text{Percentage error}=\frac{80.7-80}{80}\times 100$

$\text{Percentage error}=\frac{0.7}{80}\times 100$

$\text{Percentage error}=0.00875\times 100$

$\text{Percentage error}=0.875\approx 0.9$

Therefore, Rich's percent error in calculation is 0.9%.
