EXPLANATION:
3x= 2x+16
=> 3x-2x=16
=> x=16°
m∠1= 360 - (16+16)
= 360 - 32
= 328°
ANSWER:
x = 16°
m∠1 = 328°
Hope it helps u!
If you have a total time of 88 hrs, and you can see that totally the worker spend 11 hrs on travel, you can easily deduce that the percentage be
K=y•x
Inverse means 1/variable
y=k•1/x
y=k/x
k=y•x
x=5
y=2.4
k=2.4 • 5
k=12
Answer is:
y=12/x
Good luck.
