= 5
Answer:

Step-by-step explanation:

Lets add +5 in both the sides.


Now lets divide 12 on both the sides.


See the picture attached to better understand the problem
we know that
a full circle is a 360 degrees
divided in 12 equals parts-------> 360/12-------> 30 degrees each part
<span>the smallest angle formed by the hands of a clock at 7 o'clock has 5 parts
so
5*30</span>°------> 150°
convert to radian
pi radians---------> 180°
x ---------------> 150°
x=150*pi/180--------> x=0.83*pi radians
the answer is0.83*pi radians or 2.62 radians
1m is equal to 100cm, so the scale reduces the size of the actual object
