Question

One of the rectangular component of 25 km/hr is 15 km/hr. Find the other component

Answer 1

Answer:

20km/hr

Explanation:

Using Pythagoras theorem,

Let the remaining component be a.

⇒ a^2 + 15^2 = 25^2

⇒ a^2 + 125 = 625

⇒ a^2 = 625 - 125

⇒ a^2 = 400

⇒ a = 20

Other component is 20 km/hr.
