The yard is 60ft * 80ft = 4800ft2.
One bag covers 100ft2.
4800ft2/100ft2/bag = 48 bags
Answer:
40+95 = 135
180-135 = 45 = 3rd interior i am not sure what the two exterior angles are
Step-by-step explanation:
180 is what we subtract 135 from because in all triangles all three angles should add up to 180.
The answer is: A. 20.3
The explanation is shown below:
1. By definition, the sum of the length of the strings (The length of the blue segment and the length of the red segment) is equal to the length of the major axis (The black segment).
2. Based on this, you can write the following expression, where
is the length of the blue segment:

3. Now, you must solve for
, as following:


4. Therefore, the answer is the option A.
