let English marks =E
Maths marks = M
Science marks =S
E+M=175 ................(1)
E+S=164...................(2)
E=M+11.......................(3)
PLUGGING VALUE OF "E" IN EQUATION (2) FROM (3)
M+11 +S=164
S=153-M............(4)
PLUGGING VALUE OF "E" IN EQUATION (1) FROM (3)
M+11+M=175
2M=164
M=82
PLUGGING THIS VALUE OF 'M' IN EQUATION (4)
S=153-82
S=71
SCORE OF SCIENCE IS 71
Even after dilation the angles remain the same.
J = 101
K = 180 - (101 + 42) = 37
B = 37
Hope this helps :)
<u>Answer:</u>
when electric chargers build up on objects is called Static Electricity
<u>Explanation:</u>
When electric charges are built up on objects which can happen due to rubbing or pulling apart of some materials, we get positive charges (+) get collected on surface of one material and negative charges (-) on another. These objects stay charged for some time till they aren't transferred elsewhere through interaction.
This electrically charged surfaces creates a shock type effect when touched. This charging of surfaces of objects due to accumulation of electrons or protons is known as static electricity or static discharge.
