Question

if the clock shows the time 9 hours and 10 minutes,what is the measure of the angle made by the hour hand and the minute hand

Answer 1

Answer:

145°

Step-by-step explanation

for hour hand:    1 hour=30°  ∴9 hour=9*30=270°

10 min. is 1/6 part of hour    ∴ 10 min=1/6*30=5°

∴(9 h0urs 10 min)=270°+5°=275°

for min. hand: 1 min =6°   ∴10 min=60°

275°-60°=215°

hands of clock moves 360° ∴360°-215°=145°
