P = 2l + 2w
P = 2(8.4) + 2(4.8)
P = 16.8 + 9.6
P = 26.4cm
<em><u>Explanation</u></em>:
The only information we have to go on is that ∠AWZ ≅ ∠XYC. However, these are not specific kinds of angles that can prove lines parallel. If we had a pair of alternate interior angles, such as ∠AWZ and ∠WZY, we could say that the lines are parallel. However, we do not have enough information.
Circumference = 2 pi r = 20 pi
corresponding to 360 degrees
so an arc of 4pi feet will have a degree measure of 5pi / 20pi * 360 = 1/4 * 360 = 90 degrees
Answer: 31 teachers
Step-by-step explanation: let the number of teachers that teach in both school be x
By using venn diagram:
32 - x + x + 61 - x = 62
93 - x = 62
X = 93 - 62
X = 31
