Question

Use the formula A = Ibh find the height to the nearest tenth of a triangle with a base of 15 and an area of 200.​

Answer 1

Answer:

26.7

Step-by-step explanation:

The formula of an area of a triangle:

$A=\dfrac{1}{2}bh=\dfrac{bh}{2}$

b - base

h - height

We have b = 15, A = 200.

Substitute:

$200=\dfrac{15h}{2}$

$200=7.5h$              divide both sides by 7.5

$\dfrac{200}{7.5}=\dfrac{7.5h}{7.5}$

$h\approx26.7$
