Plzz help
Given:
Arc(AB) = 78 degrees
Measure of angle CMD = 106 degrees
To find:
The measure of arc CD.
Solution:
Secant intersection theorem: If two secant of a circle intersect each other inside the circle, then the intersection angle is the average of intercepted arcs.
Using secant intersection theorem, we get
[tex]m\angle CMD=\dfrac{1}{2}(Arc(AB)+Arc(CD))[/tex]
[tex]106^\circ=\dfrac{1}{2}(78^\circ+Arc(CD))[/tex]
Multiply both sides by 2.
[tex]212^\circ=78^\circ+Arc(CD)[/tex]
[tex]212^\circ-78^\circ=Arc(CD)[/tex]
[tex]134^\circ=Arc(CD)[/tex]
Therefore, the measure of arc CD is 134 degrees and the correct option is C.

The number line which represents the solutions that is n > -3 is number line 1.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
Any real number can be represented in two dimensions using a number line. Any number on the number line with a solid circle next to it refers to include that number followed by the rest of the values, and any number with a hollow circle refers to exclude that value from the list before the rest of the values.
The solutions represented by number line 1 are those where: n > -3.
Using special techniques, number lines are used to represent real numbers. It was Illustrated in number line 1.

Find the area of the regular polygon.
Answer:
1. 132. .2 143
Step-by-step explanation:
in isosceles trapezoid EFGH, FG parallel EH, FG=10, GH=12, and ∠E=60. Find the area of EFGH.
Answer:
22√3 units squared
Step-by-step explanation:
1) Draw the trapezoid
2) Notice you have to find the height to find the area of the trapezoid
3) Notice it is a 30 60 90 triangle when you draw the line to find the height
4) Solve for the 30 60 90 triangle and you get the height to be 2√3
5) Solve for the area of the trapezoid using this formula A= 1/2 h ( b1 + b2)
6) Fill in the numbers for the equation A= 1/2∙ 2√3 ( 10 + 12)
7) Keep aside the 1/2 for now
8) Simplify equation 2√3 + 22 or 2√3 + (10 + 12)
9) Simplify further 44√3
10) Now bring back the 1/2 and put it in the equation 1/2∙ 44√3
11) Simplify to get 22√3
12) 22√3 is the area of the trapezoid
13) 22√3 units squared is the final answer
I will put a my drawing of the trapezoid for reference and this is what I used to solve the question.
If you want to know how I solved the 30 60 90 triangle please let me know.

The question says “the system below has been solved by graphing. How many solutions does it have?”
Answer:
Infinitely many solutions
Step-by-step explanation:
3x+y=1
15x+5y=5
Step: Solve3x+y=1 for y:
3x + y +−3 x = 1 + −3x (Add -3x to both sides)
y=−3x+1
Step: Substitute−3x+1 for y in 15x+5y=5:
15x+5y=5
15x+5(−3x+1)=5
5=5(Simplify both sides of the equation)
5+−5=5+−5(Add -5 to both sides)
0=0
so there are infinite solutions

Find m∠ J
Use a calculator. Enter only a number
Answer:
26 degrees.
Step-by-step explanation:
We are given
Side KL length which is 46. (let call that side j).Side JL length which is 93( let call that side k).Angle L=90.We are trying to find angle measure of j.
Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.
[tex] \tan(x) = \frac{opp}{adj} [/tex]
[tex] \tan(x) = \frac{46}{93} [/tex]
since we are trying to find the angle measure apply inverse trig function
[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]
Plug 46 for opp and 93 for adj.
[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]
which is about 26 degrees.
