Question

What is the distance from point P(a, b)to the origin, knowing that (a + b)² = 289 and a.b = 60?

Answer 1

Answer:

13 m

Step-by-step explanation:

by distance formula , we see that under [a-0] whole square + [b-0] whole square = distance between origin and point

origin[0,0]

under root a square + b2 = distance

use [a+b]2 identity and you will get your answer
