Given:

The figure of a right triangle ABC.

To find:

The trigonometric ratios \sin B, \tan A, \cos B.

Solution:

Using Pythagoras theorem,

Hypotenuse^2=Perpendicular^2+Base^2

AB^2=AC^2+BC^2

(10)^2=(6)^2+BC^2

100-36=BC^2

64=BC^2

Taking square root on both sides.

\sqrt{64}=BC

8=BC

So, measure of BC is 8 units.

Now,

\sin \theta=\dfrac{Opposite}{Hypotenuse}

\sin B=\dfrac{AC}{AB}

\sin B=\dfrac{6}{10}

\sin B=\dfrac{3}{5}

Similarly,

\tan \theta=\dfrac{Opposite}{Adjacent}

\tan A=\dfrac{AC}{BC}

\tan A=\dfrac{6}{8}

\tan A=\dfrac{3}{4}

And,

\cos \theta=\dfrac{Adjacent}{Hypotenuse}

\cos B=\dfrac{BC}{AB}

\cos B=\dfrac{8}{10}

\cos B=\dfrac{4}{5}

Therefore, the required trigonometric ration are \sin B=\dfrac{3}{5}, \tan A=\dfrac{3}{4}, \cos B=\dfrac{4}{5}.

A certain roller coaster can accommodate 1600 riders per hour a digital sign states that there are 345 people in line if you get
sergiy2304 [10]
Given that the <span>roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

Given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

Therefore, it will take you 12.94 minutes to get to the front of the line.
