What is the value of the degree of an angle in a semi-circle?
An angle subtended at the semicircular arc is 90 degrees.
The sum of the measures of the angles is 180 degrees?
The question probably refers to the internal angles of a triangle which total 180° . Also, the angle at the centre of a circle and subtended by half the circle is 180°.
Degrees are in a circle?
There are 360 degrees around a circle
What is the measure of the angle by the straight sides of the circle divided into 5 equal parts?
A circle has no straight sides but if you mean a circle that has been divided into 5 equal sectors then the angle of each sector is 72 degrees subtended by each arc of the circle.
What is the sector area of a circle that has a radius of 8 cm and has a subtended angle of 50 degrees at the circle's centre?
Area of the sector: 50/360 times pi times 8 squared = 27.925 square cm to 3 dp
What is the angle subtended by the circumference of a circle at its centre?
It is 360 degrees because angles around a point add up to 360 degrees

Why is an inscribed angle that intercepts a semi-circle a right angle?
It is the consequence of one of the circle theorems and in some books, it is considered a theorem itself. The underlying proposition is that the angle subtended at the circumference of the circle by any arc of a circle is half the angle subtended at the centre. In the case of a semicircle, the arc is the half circle and the angle at the centre is the one that the diameter makes at the centre of the circle ie 180 degrees. So the angle at the circumference is half that ie 90 degrees.

How do you draw an angle 110 degree using ruler and compass?
Construct a circle and divide the circumference into 36 equal arcs Each arc will represent 10 degrees and 11 of them subtended to the circle's centre will create an obtuse angle of 110 degrees

How many degrees does a circle has?
There are 360 degrees around a circle
The opposite angles of a quadrilateral inscribed in a circle are?
The opposite angles of a quadrilateral inscribed in a circle are supplementary, meaning they add up to 180 degrees. This is due to the property that the sum of the opposite angles of any quadrilateral inscribed in a circle is always 180 degrees. This property can be proven using properties of angles subtended by the same arc in a circle.
