Answer:
40°
Step-by-step explanation:
The reference angle is the positive difference between an angle and the nearest multiple of 180°.
Here, the nearest multiple of 180° is -360°. The difference of interest is ...
|-320° -(-360°)| = 40°
The reference angle is 40°.
7² + 10² = c² where c = hypotenuse
49 + 100 = c²
149 = c²
c = √149 feet
72 hours because if you keep counting up by NInes 8 times you will hit 72
To answer this question, you should draw a picture of a large rectangle with labels 15 ft by 20 ft.
Inside the large rectangle, draw another rectangle (the carpet) with dimensions 9 ft by 12 ft.
When you do this, you will see that you will have 3 feet of space on both sides of the longer wall (15 - 9 = 6; 6/2 = 3 feet).
On the shorter wall, you will have 4 feet of space (20 - 12 = 8; 8/2 = 4 feet).
You will have room for your couch on the shorter wall without touching the carpet.
