Question

sides of a right triangle are a, a+d and a+2d with a&d both positive. the ratio of a to d is​

Answer 1

Answer:

3:1

Explanation:

Solution: Applying Pythagoras Theorem,

we get, (a+2d)2=a2+(a+d)2

=> a2+4d2+4ad=a2+a2+d2+2ad

=> 3d2+2ad-a2=0

=> (d+a)(3d-a)=0

neglecting (d+a)=0, by solving for (3d-a)=0, we get a:d=3:1
