Area of polygon = (number of sides × length of one side × apothem)/2
Answer:
Width = 9
Step-by-step explanation:
(P=2L+2W) = 72
L = 3W<- length is triple the width
(P = 2(3W) + 2W) = 72
P = 8W =72
W = 9
Answer:
Step-by-step explanation:
<u>Given</u>
- m∠ABC = x°
- m∠BCD = 25°
- m∠CDE = 55°
- m∠DEF = 3x°
Add two more parallel lines passing through points C and D.
Consider alternate interior angles formed by the four parallel lines.
<u>The angles between the two middle lines are equal to:</u>
- m∠BCD - m∠ABC = m∠CDE - m∠DEF
<u>Substitute values and solve for x:</u>
- 25 - x = 55 - 3x
- 3x - x = 55 - 25
- 2x = 30
- x = 15
m∠ABC = 15°
Answer: 14
Step-by-step explanation: bru is simple
Answer:
A little less than 5.
Step-by-step explanation:
An estimate means you should be able to do it in your head.
400/80 = 5 So the answer should be about 5
Can we get it a little closer? Maybe.
Divide 375 in your head by 25. It's about 15
Divide 80 by 25 which is about 3.2
15/3.2 It's under 5. but not by much. Only now can you use a calculator. The rounded answer is 4.6
