Question

The Formula A = 1/2BH can be used to find the area of a triangle. Solve the formula for H, and use your equation to find the height of a triangle with an 90 Cm2 and a base of 15 cm.
can someone help me solve it and figure out how to solve it

Answer 1

Answer: H=2A/B

H=12 cm

Step-by-step explanation:

A = 1/2BH

2A=BH

H=2A/B

H=2(90)/15

H=180/15

H=12 cm

Answer 2

Step-by-step explanation:

Substitute in the given values.

A = 90cm^2

B = 15cm

90cm^2 = 1/2 × 15cm × H

90cm^2 ÷ 1/2 ÷ 15 = H

H = 180 ÷ 15

= 12cm

The height of the triangle is 12cm.

Hope this helped! ^^
