Answer:
X = 40
Explanation: (2x) = 80
80/2 = 40
X = 40 degrees
X = 68
Since the angle opposite of it is a right angle, we know that 22 + x has to equal 90 also.
So just take 90 - 22 = 68 degrees
If order doesn't matter then the number of possible choices is:
I believe the shorter sides are 5 feet and the longer ones are 10. This is because when you add up the two shorter sides as 10, and the other two as 20, then add them up to 30. That's the perimeter. For the area, you would do 10•5 to get 50 for the area
Answer:
diameter of a circle = 12cm
Step-by-step explanation:
Area of a circle = πr²
113.04 cm² = πr²
First, search for radius (r) :-
r = √(113.04/π)
r = 6 cm
As diameter is equals to 2×radius
The diameter of a circle = 2 × 6cm
Final answer = 12 cm
