Number of angles = number of sides

180 - 120 = 60 (calculating the exterior angle)

15 less than 2 times a number is the same as 7 more than half of the number. what is the number?
romanna [79]

Answer:

x = 14 and 2/3

Step-by-step explanation:

Make an equation where x is the number.

2x - 15 = 7 + 1/2x

Then, solve the equation.

multiply both sides by 2 to get rid of the fraction

4x - 30 = 14 + x

subtract x from both sides

3x - 30 = 14

add 30 to both sides

3x = 44

divide both sides by 3

x = 14 and 2/3
