Question

If a clock shows 7 O clock find angle between hour & minute needle.​

Answer 1

Answer:

210⁰

Explanation:

the total angle of a clock is 360⁰ as it is a circle.

it will be 0⁰ when the hour and middle needle is one upon another that is 12 AM or 12 PM or basically 12 O clock.

so for every 12 hours the angle produced = 360⁰

so for 1 hour angle will be = 360/12 = 30⁰

so for 7hours the angle will be = 7× 30 = 210⁰

so at 7 0 clock the angle is 210⁰.

Answer 2

Answer:

210°

Explanation:

=> 12 parts = 360°

=> 1 part = (360°/12) = 30°

∴ θ = 7 × 30° = 210°
