I think the answer is the second one, Tessa wasn't sure how far she would swim during the first class. She would swim 3 laps during the second class. The question is confusing, because the equation s+3 is supposed to be the DISTANCE she swam in 2 classes. The problem didn't specify that distance equals laps, but I think the answer is correct
Answer:
m∠Z = 166°
Step-by-step explanation:
Since we know that the angles add up to 720°, we can set up an equation to solve for the variable x:
12x + 14x - 6 + 108 + 108 + 108 + 90 = 720
26x + 408 = 720
26x = 312
x = 12
Now we substitute the number in for x to solve ∠Z:
m∠Z = 14(12) - 2 = 166
m∠Z = 166°
