Answer:

= 8.9 units

Step-by-step explanation:

When a chord intersects with a tangent outside a circle then we use the relationship;

X ² = AO × BO, Where A and are the points of intersection of the chord an the circle, while O is the point of intersection between the chord and the tangent.

Therefore;

x² = 4 × 20 or 8 × 10

x² = 80

x = √80

= 8.944

 ≈ 8.9

Find the perimeter of the figure shown above. a. 18 yds c. 20 yds b. 10 yds d. 24 yds Please select the best answer from the cho
ycow [4]
<h3>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.
