Answer 1

Answer:

X=12

Step-by-step explanation:

*The sum of the exterior angles of a pentagon is 360 degrees.

1. Since they add up to 360, set up an equation for that:
2. (5x+4)+(4x+9)+(7x+4)+(9x-6)+(4x+1)=360 *keep the parentheses this step*
3. Remove parentheses, but don't combine like terms yet!
4. 5x+4+4x+9+7x+4+9x-6+4x-1=360
5. Ok, NOW combine like terms
6. 29x+12=360 (if my math is correct, but you should always double-check your work)
7. Subtract 12 from BOTH sides. ALWAYS subtract/add/multiply/divide from BOTH SIDES
8. 29x=348
9. Divide BOTH SIDES by 29
10. x=12
