Answer:

Trigonometry can be used to measure the height of a building or mountains

Step-by-step explanation:

if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.

The Pythagorean theorem is a^2+b^2=c^2<br> Solve for b.

rodikova [14]

Answer:

see explanation

Step-by-step explanation:

given

a² + b² = c² ( isolate b² by subtracting a² from both sides )

b² = c² - a² ( take the square root of both sides )

$\sqrt{b^{2} }$ = ± $\sqrt{c^2-a^2}$

b = ± $\sqrt{c^2-a^2}$
