Help

this is a quadrilateral

so sum of all angles is 360degrees.

therefore 120+85+53+y=360

therefore y= 360-258

therefore y = 2 degrees

y=102° so your answer is D

Step-by-step explanation:

(n-2)×180=total interior angle measure

(4-2)×180=360

360-120-85-53=102

y=102°

Hope this helps! :)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
