Answer:
E: 150
Step-by-step explanation:
Remember, a straight line is 180 degrees, and the total degrees in a triangle is 180. Also, the angle is clearly an obtuse angle, so just get rid of A, B, C, lol.
I think it would be more effective to show you this picture I made, but if you have any questions, I’ll try to answer them.

Answer:
92 ft
Step-by-step explanation:
Assume the garden has the shape shown below.
The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.
1. Around the rectangle
Distance = 28 ft + 14 ft + 28 ft = 70 ft
2. Around the semicircle
For a circle.
C = 2πr
For the semicircle,
½C =½(2πr) = πr
D = 14 ft, so
r = 7 ft
3. Total distance
Distance = 70 ft + 22 ft = 92 ft
Jordan will need 92 ft of fencing.
