Question

If the distance between the points (a,0,1) and (0,1,2) is √27 then find the value of



a.

Answer 1

Hope it may help you !!!!!

Answer 2

Step-by-step explanation:

Let P be the point whose coordinate is (a, 0, 1) and Q represents the point (0, 1, 2).

Given, PQ = √27 From distance formula Squaring both sides- a2 + 2 = 27

⇒ a2 = 25

⇒ a = ±√25 = ±5

∴ a = 5 or -5
