Answer:

there are 10 blue marbles in the bag

Step-by-step explanation:

A bag contains 60 marbles, some blue and some green. The ratio of blue marbles to green  ones is 1: 5.

Total of 60 marbles

The ration of blue to green is 1:5

1+5 = 6

Total of 6 marbles , 1 is blue

now we make a proportion. Let x be the number of blue marbles in the bag

\frac{1}{6} = \frac{x}{60}

Cross multiply it

60= 6x

Divide both sides by 6

x=10

So there are 10 blue marbles in the bag

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}}.
