Answer:
18
Step-by-step explanation:
180-160 = 20 which equals the exterior angle
the sum of exterior angles is 360 so 360/20 = the number of sides as there is an exterior angle for every side
360/20 = 18

Answer:
y = 3x.
Step-by-step explanation:
To find out the equation, put it this way. For every 3 cans, there are 9 tennis balls. So if you put it as 9/3, that means that for every can, there are 3 tennis balls. y = 3x. The x is the variable for how many cans there are. If there are 5 cans, the five would multiply by 3 and then thats your answer.

Answer:
x = 13
Step-by-step explanation:
The sum of angle measures in a triangle is 180°.
m∠M + m∠L + m∠N = 180°
(4x-4)° + (3x+12)° + (6x+3)° = 180°
13x +11 = 180 . . . . . . collect terms, divide by °
13x = 169 . . . . . . . . . subtract 11
x = 13 . . . . . . . . . . . . . divide by 13
