Answer:

853.44cm

Step-by-step explanation:

$1ft \: = 12in \\ 28ft \: = 28 \times 12in \\ 28ft \: = 336in \\ but \\ 1in \: = 2.54cm \\ 336in \: = 336 \times 2.54cm \\ 336in \: = 853.44cm$

Therefore 28ft = 853.44cm

Given:

In a right angle triangle θ is an acute angle and $\tan\theta =\dfrac{3}{5}$ .

To find:

The value of $\cos \theta$ .

Solution:

In a right angle triangle,

$\tan \theta=\dfrac{Perpendicular}{Base}$

We have,

$\tan\theta =\dfrac{3}{5}$

It means the ratio of perpendicular to base is 3:5. Let 3x be the perpendicular and 5x be the base.

By using Pythagoras theorem,

$Hypotenuse=\sqrt{Perpendicular^2+base^2}$

$Hypotenuse=\sqrt{(3x)^2+(5x)^2}$

$Hypotenuse=\sqrt{9x^2+25x^2}$

$Hypotenuse=\sqrt{34x^2}$

$Hypotenuse=x\sqrt{34}$

In a right angle triangle,

$\cos \theta=\dfrac{Base}{Hypotenuse}$

$\cos \theta=\dfrac{5x}{x\sqrt{34}}$

$\cos \theta=\dfrac{5}{\sqrt{34}}$

Therefore, the value of $\cos \theta$ is $\dfrac{5}{\sqrt{34}}$ .

Round to the nearest cent

sveta [45]

Well round to the nearest cent means to the nearest .01 So if the number is ex .0328 You round to .03 And if the number is ex .06831 You round to .07 Meaning if the number after .01 or .0_ is greater than 5 than you round up and if it's 4 or lower than you keep the number there Sorry can't do much if this is an actual problem because you only said round to the nearest cent.
