By definition, the area of the trapezoid is:
A = (1/2) * (AB + CD) * (h)
Where,
AB, CD: bases of the trapezoid
h: height
Substituting values:
A = (1/2) * (19 + 19) * (14)
A = 266 units ^ 2
Answer:
The area of the special trapezoid is:
A = 266 units ^ 2
Answer:
the correct answer for this question is
1¹/³ is 0.333'
and the second one is 1.111'
Answer:
Step-by-step explanation:
<u>Pendulum</u>
The length of the pendulum is 0.4 m or 40 cm. When swinging, it reaches the top height of 4 cm from the bottom. The geometric construction of this situation is shown in the image below.
The right triangle is formed by the length of the pendulum (40 cm), its horizontal displacement, and the vertical height projected by the pendulum.
This last distance is calculated subtracting the total length of the pendulum and the vertical displacement reached in its higher position.
We need to calculate the angle θ, for which we'll use the cosine since we know the adjacent leg and the hypotenuse:
The angle is
First you need to find out what times 4 equals 8. You should know that it is 2 because 2×4=8. Then it should look like this
and that should be your answer or what ever your problem says to do.
Hope this helped :)
