The area of a traingle is 10 sq in and the height is 5 in find the base

4in.

Step-by-step explanation:

We have several formula for finding the area of a triangle. But with this, since it involves the base and the height, we use

Area of triangle. = (1/2)bh, where b = base and h = height. The area us given and the height, to find the base, we now equate the formula above with the value which is 10 and find the base. Now

(1/2) x b x h = 10in²

b x h = 20

b x 5 = 20

5b. = 20

Therefore,

b = 4in.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
