In the figure, kj and kl are opposite rays.1=2 and km bisects nkl if m angle jkm=5x+18 and m angle4=x what is m angle4 select one a. 153 b. 33 c. 27 d. 12

the picture in the attached figure

we know that

m∠1+m∠2+m∠3+m∠4=180°

m∠jkm=m∠1+m∠2+m∠3

so

m∠jkm+∠4=180°

m∠jkm=5x+18

∠4=x

substitute

(5x+18)+x=180°------> 6x=180-18------> x=162/6--------> x=27°

therefore

the answer is

the measure of angle 4 is equal to 27 degrees

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
