GaryK [48]

Answer:

System of Equations

Step-by-step explanation:

A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used.

I think the answer is 38 degrees I just want someone to check if I am right please!
Aleksandr [31]

Answer:

JML = 142

Step-by-step explanation:

Sadly that is wrong.  Not all the angles are the same.  However, using the reflexive property we can find that angle JKM is 38 degrees.  Using this, we need to create an equation to get the other two angles.  Again, they would be the same because of the reflexive property.

38 + 38 + x + x = 360

The total needs to be 360 because the shape has 4 sides.

76+x^{2} =360

Now you beed to get the variable to one side.  To do this you would subtract each side by 76.

x^{2} =284

Finally, your answer currently shows the sum of both LKJ and JML.  to get one sides angle just divide by 2.

284 / 2 = 142

JML = 142

There is your answer.

Hope this helped.
