Question

The base of a triangle is 6 cm longer than its altitude. The area of the triangle is 80 sq cm. Find the altitude of the triangle.​

Answer 1

Answer:

10

Step-by-step explanation:

let height is x then breadth is x+6

Now , 1/2 × b × h = 80

We get ,

6x + x^2 - 160 =0

x + 16x - 10x -160 = 0

x(x+16) - 10(x+16) = 0

(x+16)(x-10) = 0

So , x = 10 ( it can'tbe negative so we don't consider 16)
