A triangle has a base of 3 feet and an area of 15 square feet. Find the triangle's height

  10 ft

Step-by-step explanation:

The formula for the area of a triangle can be used. Put the known values into the formula and solve for the unknown.

  A = (1/2)bh

  15 = (1/2)(3)h

  h = 15/1.5 = 10

The triangle's height is 10 feet.

10

Step-by-step explanation:

A=1/2*b*h

15=1/2*3*h

15=3/2*h

15=3/2h

h=15/(3/2)

h=(15/1)(2/3)

h=30/3

simplify

h=10
