Answer:

24 feet

Step-by-step explanation:

The side adjacent to the angle is given, and the hypotenuse of the triangle is the unknown. The cosine relation applies:

Cos = Adjacent/Hypotenuse

hypotenuse = ladder length = (5 ft)/cos(78°) ≈ 24.0 ft

The ladder is about 24 feet long.

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.

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

∴ The elevation of the sun is 30°
