The undefined term is C.) Plane. In geometry, the three undefined terms are point, line, and plane. Defined terms, such as angle or circle, can be defined based on the combination of undefined terms.

Hope the explanation helped!

What is area of circle that has circumference of 12pi

Burka [1]

Answer:

36pi

Step-by-step explanation:

Since the formula for the circumference is C=2*pi*r

12pi=2*pi*r we can divide and get r=6 cm

Then, we can use the formula for the area of a circle: Area=pi*r^2 and get Area=pi*6^2=36*pi.

you buy seven bags of gummy bears and 3 bag of chocolate and your total is $22 your friend buys a your friend buys three bags of

tino4ka555 [31]

Let the cost of 3 bags of chocolate be x and that of gummy be y. Thus to solve the question we form systems of equation as:
3x+7y=22...............i
x+3y=8.....ii
from ii
x=8-3y........iii
substituting iii in i we get:
3(8-3y)+7y=22
24-9y+7y=22
-2y=-2
y=1
thus the value of x=8-3*1=5
thus the price of each bag of chocolate is $5 and that of gummy is $1

In Exploration 4.1.1 problem 3 pre calc

IrinaVladis [17]

The reference triangle is a right triangle and therefore, the properties of

the reference triangle are similar to right triangle properties.

The correct options are as follows;

The reference triangle always have a leg perpendicular to the x-axis, the hypotenuse is positive, and θ is the angle adjacent to the x-axis and hypotenuse.

<h3>Reasons</h3>

The reference triangle is formed by the construction of a perpendicular

to the x-axis from the terminal side of an angle, oriented in the standard

position.

Therefore;

The reference triangle is a right triangle that always has a leg perpendicular to the x-axis.

The hypotenuse is taken as positive, given that the magnitude of the hypotenuse is the square root of the sum of the squares of the legs.

In the first quadrant, the reference angle, θ, is the same as the standard position angle and it is given by the angle formed between the x-axis and the hypotenuse side.

The correct options are therefore;

In Trigonometry it is important that the right triangle (reference triangles)

have a consistent orientation. The reference triangles always have a leg

perpendicular to the x-axis, the hypotenuse positive and the θ is

adjacent to the x-axis and hypotenuse.
