ASAP!! ITS URGENT

If the base of a triangle is 10 mm and its area is 85 mm^2 , find its altitude.

Answer 1

altitude = 17 mm

Explanation:

the area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the altitude )

given b = 10 and A = 85 , then

`(1)/(2)` × 10 × h = 85

5h = 85 ( divide both sides by 5 )

h = 17 mm
