\dfrac{1}{x}+\dfrac{1}{a}=\dfrac{1}{b}\ \ \ |subtract\ \dfrac{1}{a}\ from\ both\ sides\\\\\dfrac{1}{x}=\dfrac{1}{b}-\dfrac{1}{a}\\\\\dfrac{1}{x}=\dfrac{a}{ab}-\dfrac{b}{ab}\\\\\dfrac{1}{x}=\dfrac{a-b}{ab}\Rightarrow\dfrac{x}{1}=\dfrac{ab}{a-b}\to\boxed{x=\dfrac{ab}{a-b}}

The area of a triangle is 861 square cm. The length of the base is 82 cm. What is the height of the triangle?
Cerrena [4.2K]
Hi!

The equation to find the area of a triangle is...

(a = area
b = base
h = height)

a =  \frac{1}{2} bh

Fill in the values that we already have.
861 = \frac{1}{2}82*h
Divide both sides by 1/2
861/ \frac{1}{2}  = \frac{1}{2}/ \frac{1}{2}82*h
1722 = 82*h
Divide both sides by 82.
1722/82 = 82/82*h
21 = h

The answer is B. 21 cm

Hope this helps! :)
