In the figure,kj and kl are opposite rays.1=2 and km bisects nkl
Bess [88]

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

Solve for a side in right triangles 
defon

Answer:

AC ≈ 2.18

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan70° = \frac{opposite}{adjacent} = \frac{BC}{AC} = \frac{6}{AC}

Multiply both sides by AC

AC × tan70° = 6 ( divide both sides by tan70° )

AC = \frac{6}{tan70} ≈ 2.18 ( to the nearest hundredth )
