Answer:

KM = 10.68; angle K= 55; angle M=35  

Step-by-step explanation:

Using Law of Cosine, you can find KM. Then using Law of Sines, you can find the angle of M. Find the sum of angle M and 90. Then subtract the total of that to 180 to fine angle K.  (sidenote: your angle K should be bigger then angle M since the side measurement of K is larger than M.)

Math help please!<br> |120+x| x&lt;-120
In-s [12.5K]

Answer:

-120-x

Step-by-step explanation:

Given:

\displaystyle \large{|120+x| \quad (x < -120)}

This is the same as previous one. Recall modulus property:

\displaystyle \large{|a+x| = \begin{cases} a+x \quad (x \geq  -a) \\ -a-x \quad (x < -a) \end{cases}}

Keep in mind that |x+a| and |a+x| are equal via addition property.

Since the question gives interval of x < -120:

Therefore, the expression is -120-x
