Answer: 60°
Step-by-step explanation:
- the two angles created by CD and EF are vertical angles so they are equal
- one angle is 30° so the other one is 30° and it splits an existing 90° angle so 90-30 = 60 so x is 60°

Answer:
I believe it's C, 0.4 x 0.7
Step-by-step explanation:
13a.) If you're dividing and the base (in this case the base is 10) is the same, subtract the exponents.

13b.) If you're multiplying and the base is the same, then you add the exponents:

13c.) This is similar to 13b:

Answer:
Option (3)
Step-by-step explanation:
Area of a circle is given by the formula,
Area = πr²
Here, r = radius of the circle
Since, radius of the circular trampoline = 8 feet
Area of the cover required for the circular trampoline = π(8)²
= 64π square feet
Therefore, Option (3) will be the answer.
