mr Goodwill [35]

Answer:

The length of rope is 20.0 ft . Hence, <u>option (1) </u> is correct.

Step-by-step explanation:

In the figure below AB represents pole having height 10 ft and AC represents the rope that is from the top of pole to the ground. BC represent the ground distance from base of tower to the rope.

The rope and the ground form a 30 degree angle that is the angle between BC and AC is 30°.

In right angled triangle ABC with right angle at B.

Since we have to find the length of rope that is the value of side AC.

Using trigonometric ratios

$\sin C=\frac{\text{perpendicular}}{\text{hypotenuse}}$

$\sin C=\frac{AB}{AC}$

Putting values,

$\sin 30^\circ} =\frac{10}{AC}$

We know, $\sin 30^\circ}=\frac{1}{2}$

$\frac{1}{2} =\frac{10}{AC}$

On solving we get,

AC= 20.0 ft

Thus, the length of rope is 20.0 ft

Hence, <u>option (1)</u> is correct.

How many 1/10s in 2 3/5

Umnica [9.8K]

It'd be clearer if you'd write: "How many tenths are there in 2 3/5?"

2 3/5 13/5

---------- = ---------- = 26

(1`/10) 1/10

There are 26 tenths in 2 3/5.

3/5 of 40$ restaurant Bill

Ad libitum [116K]

Hey there Willialili!

Fraction Question::

We first have to divide the number ($40) from the denominator of our fraction (5) - This would be 8! {40 / 5}

We then multiply this with our numerator which is 3! {8 x 3}

This gives us 24!

**Answer: 40$

Hope this helped :)
