Naveen J  (7 years ago)

absolute value of [(H*30)-(M*(11/2))]
Therefore [(2*30)-(45*(11/2))] = -187.5
=187.5 degree

172.5°

In 12 hour clock, at 2 Hrs : 45 Min, minute hand is exactly at 9 and hour hand will be between 2 & 3.
Taking reference of 12, angle between 9 to 12 is 90°
Angle between 12 to 2 is 60°
In 45 min, hour hand will cover (3/4)th of 1 hr or (3/4)*30°=22.5°
So total angle between these two hands=90+60+22.5=172.5°

Is this solution Helpfull? Yes (10) | No (5)  

Naveen J  (7 years ago)

(45*(11/2))-(30*2)=187.5

prerna kumar  (6 years ago)

simple formula theta=(11/2* min-30*h)
11/2*45-30*2=187.5

Is this solution Helpfull? Yes (6) | No   

nithin shyam  (7 years ago)

The Angle Between the hands of the clock is give by,
=0.5*(60*H-11*M)
Where,
H- Hours of the clock
M- Minutes of the clock
=0.5*(60*2-11*45)
=0.5*375
=187.5 degree

Is this solution Helpfull? Yes (3) | No (2)  

M.J.Logeswari  (7 years ago)

Angle of the hour hand

HourHand_angle=0.5*(60*2+45)
=82.5

Here, The hour hand of a normal 12-hour analogue clock turns 360degree in 12 hours (720 minutes) or 0.5degree per minute.

so, that here use 0.5degree.

MinHand_angle=6*45
=270

//In MinHand rotates through 360degree in 60 mintues or 6degree per minute, So that here use 6degree(angle for per mintue)

Angle of 2hrs 45 mins=270-82.5.
=187.5

Mahendran  (7 years ago)

hour needle points to 2 and minutes needle points to 9. The angle between 9 and 12 will be 90 degree and between 12 and 2 will be 60 degree. so totally 150 degree.................

Is this solution Helpfull? Yes (1) | No (6)  

saisurendar  (7 years ago)

Hours hand angle is 150 degree
Mins hand angle is 360 degree

Is this solution Helpfull? Yes (1) | No   

sivasailam  (6 years ago)

every 5 min is equal to 30 degree
therfore from 45 to 2 the degree is 30+30+30+30+30=150 degree
since it is 2:45
the hour hand traveled about 3/4 distance from 2
therfore its angle is 3/4*30=22.5 degree
therefore total angle=150+22.5=172.5 degree

Is this solution Helpfull? Yes (1) | No   

karthick  (7 years ago)

Answer is 217 every 5 min = 30 so 2.45 between 7 five min

Is this solution Helpfull? Yes | No (1)  

Priya Dharshini  (7 years ago)

NILA  (6 years ago)

the formula for finding the angle between the min hand and hr hand is
(H*30)-(11/2*M)
thus 2*30-11/2*45=187.5 degree

Is this solution Helpfull? Yes | No   

Muthulakshmi  (6 years ago)

Hour hand: It travels 360 degrees in 12 hours. So for 2 hours it travels 60 degrees((360*2)/12).
Minute hand: It travels 360 degrees in 60 minutes. So for 45 minutes it travels 270 degrees((360*45)/60).
Angle between them = 210 degrees(270-60)
