Explanation:

The triangle is a special right triangle.

Since it has a 45° in one of the two unknown angles, the other angle is also 45°. This is called a 45-45-90 right triangle.

The rule for that special triangle is that the legs measure the same while the hypotenuse measures a multiplication of √2.

Since one leg is labeled 7 units, the other (which is x) is labeled 7 too.

Morgarella [4.7K]

Answer: 21 m

Step-by-step explanation:

Given

the angle of depression of point G is $25^{\circ}$

Distance from pole base to point G is 45 m

Suppose h is the height of the pole

From the figure, we can write

$\Rightarrow \tan 25^{\circ}=\dfrac{h}{45}\\\\\Rightarrow h=45\tan 25^{\circ}\\\Rightarrow h=20.98\approx 21\ m$
