Answer:
bottom one
Step-by-step explanation:
Because it's tall and if it was the same as the circumference it would have been wide
B, it should add up to 180 degrees
U/9 = 8/12 u = 6
Step 1: Cancel the common factor (4)
u = 2
—- —-
9 3
Step 2: multiply both sides by 9
9u 2 * 9
—- = ——-
9 3
Step 3: simplify
2 *9 = 18
18 ÷ 3 = 6
u = 6
One goes up and down and the other goes side to side
U add 1.5 everytime
so the next 3 terms: 8, 9.5 and 11
