Write a story that could represent this math problem. (4 points) A rectangle partitioned into thirds five times. The first part, the second part, the fourth part, the fifth part, the seventh part, the eighth part, the tenth part, the eleventh part, the thirteenth part, and the fourteenth part are shaded.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
