1 answer:

4 0

Answer:

A horizontal line is a line that is parallel to the x-axis of the coordinate plane and its equation is of the form y = b, where 'b' is constant, whereas, a vertical line is a line parallel to the y-axis and its equation is of the form x = b, where 'b' is constant.

What is the difference between a day and a line segment

zepelin [54]

Hello!

I do believe you meant to say:

"What is the difference between a ray and a line segment?"

The difference between a ray and a line segment is:

A ray has one endpoint and continues in one direction. a ray is infinite

A line segment has two endpoints. a line segment is finite

I hope this helps, and have a nice day!

An electric pole is 10m high if it's shadow is 10×√3 in length find the elevation ofthe sum

lianna [129]

First, Look at the attached picture as a reference.

Now, using Pythagoras theorem,

$AC^2=AB^2+BC^2 \\\\AC=\sqrt{AB^2+BC^2 }\\\\AC=\sqrt{10^2+(10\sqrt3)^2}\\\\ AC = \sqrt{100+300}\\\\AC=\sqrt{400}\\\\AC=20~in.$

Now, lets find the elevation of the sun.

 $tan\theta = \frac{AB}{BC} \\\\ tan\theta = \frac{10}{10\sqrt3} \\\\ \theta = tan^{-1} \left(\frac{10}{10\sqrt3}\right) \\\\ \boxed{\theta = 30 \°}$

∴ The elevation of the sun is 30°
