Answer: D) 5.5</h3>
==================================
Work Shown:
MN = x
ML = 6
JN = 8.8
JK = 9.6
----------
Triangle MNJ is similar to triangle LNK, so the corresponding pieces form a proportion as shown below
MN/ML = JN/JK
x/6 = 8.8/9.6 plug in given values
x/6 = 0.91667
x = 6*0.91667 multiply both sides by 6
x = 5.50002
x = 5.5
MN = 5.5
x,z,y = 20,15,-33
i think thats it im sorry
There are many ways to do this. Such ways are using the quadratic formula, completing the square, etc.
We have
We can add 46 to both sides so the -21 becomes a +25. by doing that, we get
This can be wrote as
We solve the square root and get
(The +- is a plus minus sign.) Subtract five on both sides to get
The answer is
C.
Answer:
Angle b is 90 degrees. If angle a is 42 degrees and it is a right triangle then angle b is 90 degrees
