The answer would be 13 because if you put 7 over 56 and on the other side put 104 on the bottom. You multiply 7 by 104 and get 728 and after that you divide it by 56 and get 13.

Please please please help!!!
aleksandr82 [10.1K]

Answer:

a = 35, b = 40, c = 17.5

Step-by-step explanation:

The sum of the 3 arcs on the semicircle above the diameter = 180° , that is

65 + 80 + a = 180

145 + a = 180 ( subtract 145 from both sides )

a = 35

The inscribed angles b and c are half the measures of their intercepted arcs

b = \frac{1}{2} × 80 = 40

c = \frac{1}{2} × 35 = 17.5

Frequency is the amount of times a certain data value appears in a data set, so we need to look for the data value that appears the highest amount of times. Since the correct answer is not explicitly stated, then we need to pick the answer choice that makes the most sense.

Your answer is 1/16
