A pole, 4m high, stands, vertically, on

Lostsunrise [7]

Answer:

Length of the shadow of the pole is 6.93 metres

Step-by-step explanation:

Given:

Height of the pole = 4 m

The angle sun makes with the horizontal = 30 degrees

To Find:

Length of the shadow of the pole = ?

Solution:

The tangent ratio is the value received when the length of the side opposite of angle theta is divided by the length of the side adjacent to angle theta

Let x be the length of the shadow

According to the tangent ratio

$tan {\theta} = \frac{opposite}{adjacent}$

On substituting the values,

$ta( {30^{o}) = \frac{4}{x}$

$x = \frac{4}{tan ({30^{o})}}$

$x =\frac{4}{0.57735027}$

x = 6.93 m

I'd really appreciate your help, please no joke answers

Lerok [7]

Answer:

d= 2√10

Step-by-step explanation:

y= 3x - 5

3x - y - 5=0

d= | 3* 7 +(-1) * (-4) + (+5) |

________________

$\sqrt{3^{2} } + (-1)^{2}$

d = | 20 | / $\sqrt{10}$

d = 20 / $\sqrt{10}$

d = 2 $\sqrt{10}$
