What is the answer need ASAP

ANSWER


C. 58°


EXPLANATION


The sum of the interior angles of a triangle is 180°.


We sum all the three angles to obtain,


8x+(14x+2)+(10x+50)=180.


We group like terms to get,



8x+14x+10x+2+50=180.


Simplify,



32x+52=180.


Combine like terms to get,


32x=180-52.


Simplify,


32x=128.



Divide both sides by 32 to get,



x=4.


We substitute the value of x into the expression for



m\:.


This implies that,


m\:.



m\:.



m\:.



The correct answer is C

What is the value of x in the figure shown below?
satela [25.4K]

50?

I'm assuming 50 because the angles to a triangle always adds up to 180 and this one has 130 and 130+50=180
