Answer:
252°
Step-by-step explanation:
In the figure attached, the diagram is shown. There, we can see that
∠DOB = ∠AOD + ∠AOC + ∠COB
Replacing with the equivalences: ∠DOB has a measure of 3.5y, the measure of ∠AOD is y, and ∠AOC + ∠COB measure 180°, we get:
3.5y = y + 180°
3.5y - y = 180°
2.5y = 180°
y = 180°/2.5
y = 72°
Therefore, ∠DOB = 3.5*72° = 252°
The answer would be C. 8 cm, 15 cm, 22cm.
The rule is that the two smaller sides when added, have to be bigger than the largest side. 8 + 15= 23 and the largest side is 22. 23 is greater than 22. The other options do not work with this rule
Answer:
Around 37, first one
Step-by-step explanation:
add up all the 7th grader number, 40
125 divided by 40 is around 3.125
3.125 times 12 = 37.5
37 because there is no half a kid
Circumference= pi times diameter
steps:
1. Divide 82.268 by 3.14 which is 26.2
2. 26.2= diameter ,so we he have to divide it by 2 to get the radius which is 13.1
3. Your answer is C. 13.1 inches
