IM IN A HURRY PLEASE HELP ME QUESTION IS DOWN BELOW WORTH 15 POINTS each

Answer 1

A circle is a shape formed by a curved side. Therefore, the required answers are:

1. An example of an inscribed angle is: <SQT or <QST or <QTS

2. An example of a minor arc is: arc QT or RS or QR

3. An example of a semicircle is: QRS or QTS

4. <QPR =  $\frac{264600}{44r}$ degrees

An angle is said to be formed whenever two or more straight lines intersect or meet. But an inscribed angle is an angle formed within a given circle.

A circle is a shape formed by a curved side. Some of its parts are semicircle, radius, diameter, chord, sector, segment, etc.

Thus the following can be deduced from the given question:

1. An example of an inscribed angle is: <SQT or <QST or <QTS

2. An example of a minor arc is: arc QT or RS or QR

3. An example of a semicircle is: QRS or QTS

4. <QPR.

length of an arc = $\frac{x}{360}$ 2$\pi$r

where r is the radius of the circle

105 =   $\frac{x}{360}$ x 2 x $\frac{22}{7}$ x r

      = $\frac{44xr}{2520}$

44 xr = 105 x 2520

44xr = 264600

x = $\frac{264600}{44r}$

Therefore the measure of angle QPR in terms of r is  $\frac{264600}{44r}$ degrees.

5. The length of arc QTR can be determined by;

Arc QTR =  $\frac{x}{360}$ 2$\pi$r
