Answer:

42°

Step-by-step explanation:

Theorem of isosceles triangle says that the two adjacent angles that are not connected by two congruent lines are congruent.

Simple words:

L is the angle connected by both lines with the "ticks"

So that means K and M are congruent

Since K = 42°

M = 42°

Fun fact: If the angle name is something like ABC, the angle is technically B, because B is the vertex.

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

A ball slides up a frictionless ramp. It is then rolled without slipping and with the same initial velocity up another frictionl
KATRIN_1 [288]

Answer:

Rolling case achieves greater height than sliding case

Step-by-step explanation:

For sliding ball:

- When balls slides up the ramp the kinetic energy is converted to gravitational potential energy.

- We have frictionless ramp, hence no loss due to friction.So the entire kinetic energy is converted into potential energy.

- The ball slides it only has translational kinetic energy as follows:

                                   ΔK.E = ΔP.E

                                   0.5*m*v^2 = m*g*h

                                    h = 0.5v^2 / g

For rolling ball:

- Its the same as the previous case but only difference is that there are two forms of kinetic energy translational and rotational. Thus the energy balance is:

                                  ΔK.E = ΔP.E

                                  0.5*m*v^2 + 0.5*I*w^2 = m*g*h

- Where I: moment of inertia of spherical ball = 2/5 *m*r^2

             w: Angular speed = v / r

                               0.5*m*v^2 + 0.2*m*v^2 = m*g*h

                               0.7v^2 = g*h

                               h = 0.7v^2 / g

- From both results we see that 0.7v^2/g for rolling case is greater than 0.5v^2/g sliding case.

What is the inverse of the function F(x)=x^2 <br><br> Please help me..
ikadub [295]
Firstly make the f(x) = x and x = y:
x = y^2 
Then solve for y:
√x = y
Hopefully this helps and let me know if you have more questions!
