It's dividing by 2.
Next 3 would be: 25, 25/2, 25/4 or converting those into decimals.
Answer:
53.8°
Step-by-step explanation:
Use cosine law
67² = 72² + 76² - 2(72)(76)cosX
cosX = 719/1216
X = 53.75190075
Given:
Solution
We are required to solve the equation for c.
First, we open the bracket:
Next, we make c the subject of formular:
Answer: c = 8

Answer: 24 yards, choice D</h3>
There are 4 sides to this figure (trapezoid). The left slanted side and the right most vertical side, combined with the top and bottom horizontal sides, will get us the perimeter.
left slanted side = 5 yards
right most vertical side = 4 yards (see note below)
bottom side = 9 yards
top side = 6 yards
Add up the four sides mentioned: 5+4+9+6 = 9+15 = 24
note: the rectangle has opposite sides that are the same length. While the right most side isn't labeled, it is the same length as the left side of the rectangle, so both are 4 yards long.
Another thing I should probably mention is that we do not add in the interior 4 yard side. The perimeter is only the outer or exterior sides we care about. Think of it like we're trying to fence around some property lot and we don't want to subdivide the property up. Finding the perimeter will help us find the amount of fencing needed to surround the property.
