Substitution: 45+15(6-1)
Simplify: 120
Step-by-step explanation:
Calculate within parenthases (6-1) =5 =45+15(5)
Multiply left to right 15(5)=75 =45+75
Add leftg to right 45+75=120
Answer = 120
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.

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

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.
H and N are congruent because they are both 58 degrees,
J and L are congruent because they are both 62 degrees,
and K and M are congruent because they are both 60 degrees.
Therefore triangle HJK is congruent to triangle NLM.
