Answer:
91 + 125 + 92 +(3x-5) + (4x- 8)= 540
308 +3x -5 +4x -8 =540
7x - 295 = 540
7x = 540 -295
7x = 245
x = 245/7
x = 35
Step-by-step explanation:
Answer:
x=35²
Step-by-step explanation:
1. Since all pentagons have a total interior angle sum of 540, add all the terms together and set them equal to 540:
[tex]91+92+125+\left(4x-8\right)+\left(3x-5\right)=540[/tex]
2. combine like terms. (91, 92, -8, -5 and 125) (3x and 4x)
[tex]295+7x=540[/tex]
3. subtract 295 from 540:
[tex]7x=540-295\\7x=245[/tex]
4. Divide 245 by 7.
[tex]\frac{7x}{7}=\frac{245}{7}\\\\x=35[/tex]
Final answer:
x = 35
