Answer:
a)5 b)15
Step-by-step explanation:
5 times 11=55
15 times 3 is 45
add together is 100
5+15 is 20 questions

Here we go ~
1. A circle can be named by their Centre, so here in the diagram it's :
2. Name 4 radii :
Radii are the line segments that joins the centre and boundary of circle.
They are :
3. 2 Major arcs :
considering two points on a circle, and joining them forms a curve ( you can say part of circumference )
When we consider two points two arcs are formed and the arc with more length is known as Major Arc
That is :
- Major arc ECF
- Major arc BEC
4. A Semicircle :
Semicircle is special arc which is formed when two arcs formed by the points are equals to one another... it's also half the Perimeter of circle.
that is :
5. 3 minor arcs :
The arc formed by two points having lesser length is known as minor arc.
that is :
6. 3 Central angles :
Central angles are angles formed by arcs on centre of the circle ~
that is :
- Angle FAB
- Angle BAC
- Angle GAB
7. A diameter :
Diameter is a chord that passes through centre of the circle.
8. Congruent Angles :
In the given figure, there are two equal/congruent angles that are ~
9. Adjacent arcs :
The arcs that have one common end point are known as Adjacent arcs ~
that are :
Only 3 and 9 are both the subset of odd numbers and the subset of multiples of 3.
The measure of the unknown angle in the full circle is calculated as: 310 degrees.
<h3>What is the Measure of a Full Circle?</h3>
The angle measure of a full circle equals 360 degrees.
The full circle given is divided into two angles, of which 50 degrees is a measure of one of the angles.
The unknown angle = 360 - 50 = 310 degrees.

Answer:
Step-by-step explanation:
Distance = speed * time
- d = 12 *1 1/2 = 12*1.5 = 18
