Question

Please help. find the missing side​

Answer 1

x = 10

Explanation:

This is because the formula of the area of a triangle is b x h divided by 2.

Since 8 is the base, you have to find what to multiply it by to get 80 (since 80 divided by 2 is the answer, 40).

80 divided by 8 is 10, therefore the base, or x, is 10.

You can put it in the formula to double check and it will equal 40.
