Answer 2

Hey there!

Consider clock to be 360° so 12 marking = 360

360/12 = 30 degrees per hour

1=30° like wise,

Where will the hour hand of a clock stop if it starts (a) From 6 and turns through 1 right angle?

6 o' clock = 6* 30 = 180 °

From 180, a turn of right angle

180+90/ 30= 270/30= 9

So the hour hand would be at ' 9 '

===============================

Where will the hour hand of a clock stop if it starts (b) From 8 and turns through 2 right angles?

8 o' clock = 8* 30° = 240°

240+2*90= 240+180= 420°

420/30= 14

as 14>12 subtract 12 from 14

So, the hour hand would be at 2 o' clock

===================================
Where will the hour hand of a clock stop if it starts. From 10 and turns through 3 right angles?

10 o' clock = 10* 30° = 300°

300+ 3*90 = 570/30 = 19


as 19>12 subtract 12 from 19

So, the hour hand would be at 7 o' clock


==================================
Where will the hour hand of a clock stop if it starts. From 7 and turns through 2 straight angles

7 o' clock = 7* 30 = 210 °

210+ 2 * 180 = 210+360 = 570/30= 19

as 19>12 subtract 12 from 19

So, the hour hand would be at 7 o' clock again

===========================

hope helped!
