Question

n the given figure, if l | | m and a : b = 2 : 3 then find the value of y.​

Answer 1

Given :-

In the figure L l l M and a:b = 2:3

To Find :-

Value of y

Solution :-

Angle B = Angle Y

As they are corresponding lines

Now

Let the ratio be 2x and 3x

$\tt \: 2x + 3x = 180$

$\tt \: 5x = 180$

$\tt \: x \: = \dfrac{180}{5}$

$\tt \: x \: = \cancel \dfrac{180}{5}$

$\tt \: x \: = 36$

Now,

$\tt \therefore \: 3x = 3(36) = 108 \degree$

$\tt \therefore \: y = 108 \degree$

Answer 2

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
