5hrs10mit.
60mit =30°.
5°+5°+5°+5°+5°+5°/10mit.
5hrs*30° =150°.
10mit/5°.
150° +5°= 155°
60mit =30°.
5°+5°+5°+5°+5°+5°/10mit.
5hrs*30° =150°.
10mit/5°.
150° +5°= 155°

Hello everyone.
min=10 past=5 it means,
10 hours 5 min,
so, 10+5/60 = 31/6,
Therefore, hour hand = (360/12 * 31/6) = 155 Ans.
min=10 past=5 it means,
10 hours 5 min,
so, 10+5/60 = 31/6,
Therefore, hour hand = (360/12 * 31/6) = 155 Ans.

If 1hr=30degrees.
Then 5hrs= (5*30) =150degrees.
And then 10min= (10/60) =1/6.
1/6*30=5degrees.
The total is 155degrees.
Then 5hrs= (5*30) =150degrees.
And then 10min= (10/60) =1/6.
1/6*30=5degrees.
The total is 155degrees.

To Uma
5 hr 1o min=310min(5*60+10)
=310/60 hr
=31/6 hr.
or
5 hr 10 min=5+10/60
=31/6
5 hr 1o min=310min(5*60+10)
=310/60 hr
=31/6 hr.
or
5 hr 10 min=5+10/60
=31/6

1hrs=30°
So 5 hrs 10min =(5+1/6)*30°. i.e
1hrs = 60min
1min =1/6
10min = 10/60 = 1/6
= (31/6)*30.
= 155°.
So 5 hrs 10min =(5+1/6)*30°. i.e
1hrs = 60min
1min =1/6
10min = 10/60 = 1/6
= (31/6)*30.
= 155°.

Angle = 30H-11/2Min.
Therefore for 5:10 ANGLE IS 30 * 5-11/2 * 10 = 150-55 = 95 degrees.
This is the correct answer.
Therefore for 5:10 ANGLE IS 30 * 5-11/2 * 10 = 150-55 = 95 degrees.
This is the correct answer.

12-5.10 = 5hr 10min
1hr=30 °.
5hr = 5 * 30=150
1min =1/2 °.
10min =10 * 1/2=5.
Ans) 150 + 5=155°.
1hr=30 °.
5hr = 5 * 30=150
1min =1/2 °.
10min =10 * 1/2=5.
Ans) 150 + 5=155°.

1 hr = 30° and 1 min = (1/2)°,
So , 5 hrs = 150 min and 10 min = 5°,
Thus 150 + 5 = 155°.
So , 5 hrs = 150 min and 10 min = 5°,
Thus 150 + 5 = 155°.

5.10 hr.
1hr = 30°.
5hr = 30 × 5= 150.
10min = 10 ÷ 60 = 1/6,
The 1/ 6 ×30 = 5°,
Then add 150 + 5 = 155°.
1hr = 30°.
5hr = 30 × 5= 150.
10min = 10 ÷ 60 = 1/6,
The 1/ 6 ×30 = 5°,
Then add 150 + 5 = 155°.

Also, apply the formula;
Q = 30H + 1/2M.
Put the value of Hour and minutes.
30 * 10 + 1/2 *5,
= 155.
Q = 30H + 1/2M.
Put the value of Hour and minutes.
30 * 10 + 1/2 *5,
= 155.
