Answer:
If im correct, 50.26
Step-by-step explanation:
Just use the radius to find the area as if it was a normal circle than divide by 4
1. 180-146=34°
2. 40° (alternate angles are equal)
3. 50° (vertically opposite angles are equal)
4. 180-75=105° (co-interior angles add up to 180°)
5. 90-65=25°
Hope my answer helped u :)
It's A. If an instrument is a piano, then it has keys.
The given convex polygon has 7 sides
Hence its sum of interior angles is given by the formula , (number of sides-2)x180°
=> (7-2) x 180°
=> 5 x 180°
=> 900°
The sum of all angles must be equal to 900°
The given six angles are :
139°,126°,106°,129°,141°,112° , x°
=> 139+126+106+129+141+112+x = 900°
=> 753 + x = 900
=> x = 900-753
=> x = 147°
Hence 147° is the required answer.
