Exterior angle = 180 - 144 = 36 degrees
Number of sides = 360 / 36 = 10 sides (answer)
Answer:
3n - 5
Step-by-step explanation:
f(n) = 3n - 5. Works for all of them
Let x represent the number.
"three times a number" is 3x
eight less than "three times a number" is 3x-8
"is more than 22" is "> 22"
Your inequality is
3x-8 > 22
All sides of a triangle must add up to 180. 89 + 59 = 148. 180 - 148 = 32.
Answer:
1) 
°
2) 
°
Step-by-step explanation:
1)
As these two angles are supplementary (They add together to equal 180°) we can setup the equation and solve for x.
2)
Again, these two angles are supplementary we can setup the equation and solve for x
