Answer:
X=12
Step-by-step explanation:
*The sum of the exterior angles of a pentagon is 360 degrees.
- Since they add up to 360, set up an equation for that:
- (5x+4)+(4x+9)+(7x+4)+(9x-6)+(4x+1)=360 *keep the parentheses this step*
- Remove parentheses, but don't combine like terms yet!
- 5x+4+4x+9+7x+4+9x-6+4x-1=360
- Ok, NOW combine like terms
- 29x+12=360 (if my math is correct, but you should always double-check your work)
- Subtract 12 from BOTH sides. ALWAYS subtract/add/multiply/divide from BOTH SIDES
- 29x=348
- Divide BOTH SIDES by 29
- x=12
