A ∩ B is the set that contains elements common to set A and set B.
here its {10 40 60}
Answer:
Arc Measure: In a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc. Arc Length: In a circle, the length of an arc is a portion of the circumference. The letter "s" is used to represent arc length.
Step-by-step explanation:
Answer:
a) a = 60° b = 60° c = 120° d = 60°
b) a = 140° b = 20° c = 60° d = 60°
Step-by-step explanation:
a) Sum of the angles of a hexagon = (6 - 2)180 = 720
Since the hexagon is regular, c = 720/6 = 120
a and c are supplementary, so a = 180 - 120 = 60
d = 120/2 = 60
b)
sum of the angles of a nonagon = (9 - 2)180 = 1260
a = 1260/9 = 140
140 + 2b = 180
2b = 40
b = 20
c = 60 and d = 60 (This is really difficult to explain with the vertices being labeled)
The answer to the question
Answer:$1.25
Step-by-step explanation:
2 divided by 1.60=$1.25
3 divided by 2.40= $1.25
5 divided by 4.00= $1.25
8 divided by 6.40 = $1.25
