Answer:
78.539816 ft²
Step-by-step explanation:
To calculate a circle's area you have to multiple pi with the square of the circle's radius (the radius of a circle is half of its diameter): π·5ft²
5ft² = 5ft·5ft = 25ft
π = 3.14159...
Answer: 30° and 110°
55° and 85°
70° and 70°
The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:
= 180° - 40°
= 140°
Therefore,
30° + 110° = 140°
55° + 85° = 140°
70° + 70° = 140°
