1 1/2? I pretty sure this is the answer.
Answer:
x = 6
Step-by-step explanation:
Given
3x + 30 + x = 10 + 2x + 5x + 2 , simplify both sides
4x + 30 = 7x + 12 ( subtract 7x from both sides )
- 3x + 30 = 12 ( subtract 30 from both sides )
- 3x = - 18 ( divide both sides by - 3 )
x = 6
Answer:
decagon is 36° 20-gon is 18°
Step-by-step explanation:
divide de number of sides by 360
N/360
10/360= 36
Put in slope intercept form so the first equation would be y=-x-9 then the second one will be y=-5/2x-16
