Answer:
141°
Step-by-step explanation:
It's an octagon so the Sum of interior angles is: (8-2)×180=1080
5x+133+16+126+162-12+30=5x+455=1080
5x=625
x=125
x+16=141
Answer:
2.5
Step-by-step explanation:
(I'm assuming you're doing this the same way I learned it, if not I'm sorry if it doesn't make sense)
=
Cross multiply
12x=30
Divide
x=2.5
This is just one way to do the problem. An easier way is to simplify the fractions.
=
You can either cross multiply or figure out that 2 is half of four and simply divide 5 by 2 which will also result in 2.5

1.k^2+5k-6=0
a=1
b=5
c= -6
disctirminant =b^2-4ac
disctirminant =5^2-4.1. (-6)
disctirminant =49
x1= -(5)+ square root of 49/2.1
x1=-5+7/2
x1=1
x2= -5- square root of 49/2.1
x2= -5-7/2
x2= -6
