Answer:
Step-by-step explanation:
6x + 12 + 4x + 8 = 180 {Linear pair}
6x + 4x + 12 + 8 = 180 {Combine like terms}
10x + 20 = 180 {Subtract 20 from both sides}
10x = 180 - 20
10x = 160 {Divide both sides by 10}
x = 160/10
x = 16
m∠KLJ = 6*16 + 12
= 96 +12
= 108
m∠JLM = 4*16 + 8
= 64 + 8
= 72
I believe this is Pythagorean theorem
The equation is
a^2+b^2+=c^2
In this case the equation would be
6^2+4^2=c^2
36+16=c^2
52=c^2
c=7.21110255093

Answer:
72 degrees
Step-by-step explanation:
Calculate the number of sides in the regular polygon. We do this by dividing 360° by the size of one exterior angle, which is 72°
