Answer:
125°
Step-by-step explanation:
The angles in a qadrilateral always adds up to 360° so to get the fourth angle, you add the angles given and subtract it from 360°
72°+98°+65°+x = 360°
235°+ x = 360°
x = 360°-235°
x = 125°
The area of a whole circle is (pi) (radius²) .
So the area of half of it would be <em>(1/2) (pi) (radius²) .</em>
If you don't know the radius, then you can use the formula
Area = (1/8) (pi) (diameter²) .
