Answer:
s = 130 degrees
Step-by-step explanation:
decagon has a 1,440 degrees interior angles
equation: 1,440 = s + 1310
to find s, add all the known angles
⇒ s + 150 + 170 + 160 + 130 +120 + 160 + 105 + 160 +155
⇒ s + 1,310
equation:
s + 1310 = 1440
subtract each side by 1310
⇒ s + 1310 - 1310 = 1440 - 1310
⇒ s = 130
Answer:
D
Step-by-step explanation:
Given
- 8 < 4 ( add 8 to both sides )
< 12
Multiply both sides by 4 to clear the fraction
j < 48 → D
Answer:
Your answer would be 12

Hopefully this helped, if not HMU and I will try my best to get you a better answer! :)
Answer:
How bout no-_-
Step-by-step explanation:
You not smart
What you do first is add 4 to both sides of the equation to get x alone and you get x=11. X is equal to 11.
