Answer:
7
Step-by-step explanation:
x equals a certain number
3x - 2 = 19
add 2 both sides
3x=21
divide 3 both sides
x=7
20 degrees if you take a protractor if will come out to the 20
Yes, the correct answer is C, I believe..?
Answer:
m<B=m<K=100
m<A=m<J=133
m<L=m<C=41
m<M=m<D=86
Step-by-step explanation:
Since
, the corresponding angles are congruent.
This implies that:

m<L=41=m<C
m<M=86=m<D
The sum of angles in a quadrilateral is 360 degrees.
m<B+133+41+86=360
m<B+260=360
m<B=360-260
m<B=m<K=100
