Question

What is m∠JNM? Enter your answer in the box below.

Answer 1

10x° would be the answer

Answer 2

we know that

we know that

Vertical angles are congruent angles opposite each other where two lines cross

so

in this problem

m∠JNM=m∠KNL

so

substitute the values

$4x+6=7x-21\\7x-4x=6+21\\3x=27\\x=27/3\\x=9\°$

Find the  m∠JNM

$(4x+6)=(4*9+6)=42\°$

therefore

the answer is

The measure of angle JNM is $42\°$
