Answer:
∠C = 122° and ∠D = 80°
Step-by-step explanation:
This is a cyclic quadrilateral.
Definition: A cyclic quadrilateral is a quadrilateral (a four-sided two-dimensional shape) drawn inside a circle. Every vertex of the quadrilateral must touch the circumference of the circle.
The opposite angles in a cyclic quadrilateral add up to 180°.
Therefore, ∠A + ∠C = 180° and ∠B + ∠D = 180°
To find the value of ∠C:
∠A + ∠C = 180
∠C = 180 - ∠A
∠C = 180 - 58
∠C = 122°
To find the value of ∠D, first find the value of y:
∠B + ∠D = 180
(3y + 4) + (2y + 16) = 180
5y + 20 = 180
5y = 180 - 20 = 160
y = 160 ÷ 5 = 32
Therefore, y = 32
To find ∠D, substitute found value of y into the expression for ∠D:
∠D = 2y + 16
∠D = 2 x 32 + 16
∠D = 80°

3+2x-y=0
-3-7y=10x
Answer: x=-1 y=1
Step-by-step explanation:
solve y in 3+2x-y=0
y=3+2x
sub y=3+2x into -3 -7y=10x
-14x- 24= 10x
solve x in -14x-24=10x
x= -1
sub x= -1 into y =3+2x
y=1
so therefore x= -1 and y=1
In this figure, lines m and n are parallel and intersect transversal t. Also, m∠8=78° .
What is m∠2 ?
12º
78º
102º
I don't know.
Answer: The answer is 78
Step-by-step explanation: I had just taken the quiz
The measure of angle 2 is 78°. Therefore, option C is the correct answer.
Given that, lines m and n are parallel and intersect transversal t.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
From the figure given m∠8=78°
m∠8=m∠6 (Vertically opposite angles are congruent)
m∠6=78°
m∠6=m∠2 (Corresponding angles on parallel line are equal)
So, m∠2=78°
The measure of angle 2 is 78°. Therefore, option C is the correct answer.

It is equal for Group A and Group B. It is greater for Group B than Group A. Its value for Group A is double the value for Group B. Its value for Group B is double the value for Group A.
The mean is equal for Group A and Group B.
GivenTwo groups of students were asked how far they lived from their school.
The table shows the distances in miles:
Group A (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2

What is mean?The mean of any data set or observation is equal to the sum of all the observations and divided by the number of observations.
The formula used to calculate the mean is;
[tex]\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}[/tex]
The mean of group A is;
[tex]\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}\\\\\rm GroupA \ mean = \dfrac{1 + 1.5 + 3.03 + 3.2 + 2.8 + 1.5 + 1.8 + 2.5 + 2.2}{9 }\\\\\rm Group A \ mean=\dfrac{ 19.53}{9}\\\\ Group A \ mean = 2.17[/tex]
The mean of group B is;
[tex]\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}\\\\\rm Group B \ mean = \dfrac{2 + 2.5 + 3.23 + 1.3 + 1.8 + 2.4 + 3 + 1.5 + 1.8}{9} \\\\Group B \ mean = \dfrac{19.53}{9}\\\\ Group B \ mean = 2.17[/tex]

[tex] = 40\%[/tex]
40℅ of the students likes to play tennis
hope this helps you
Answer:
40% Use the ratio method
Step-by-step explanation:
Since
10 : 25 = X : 100
Then we know
10/25 = X/100
Multiplying both sides by 100 cancels on the right
100 × (10/25) = (X/100) × 100
100 × (10/25) = X
Then solving for X
X = 100 × (10/25)
X = 40
Therefore
10 : 25 = 40 : 100

Solve by Factoring (4m +2 )(3m - 9)= 0
i think i know but looking at peoples answer now i am reconsidering my choices but anyway good luck i think u should use the other guy solution but anyway have a good day :>
Explanation:
The equation is already factored for us (well nearly so).
Set each piece equal to zero. Refer to the zero product property.
4m+2 = 0 solves to m = -1/2. Subtract 2 from both sides, then divide by 4 to get m = -2/4 = -1/2.3m-9 = 0 solves to m = 3. You add 9 to both sides, then divide by 3 to isolate m.The two roots are -1/2 and 3. If you were to substitute either value into the equation, then you should get 0 on both sides after simplifying.

Find the fraction that is halfway between 1/4 and 2/7?
Answer:
15/56
Step-by-step explanation:
To get the answer, you find the least common denominator of 4 and 7 which is 28. 1/4 is equal to 7/28. 2/7 is equal to 8/28. if you subtract 7/28 from 8/28, you get one twenty-eighth (1/28). Half of 1/28 is 1/56. To add 1/56 and 7/28, multiply the numerator and denominator of 7/28 by 2. You will get 14/56. Add 14/56 and 1/56 and the answer is 15/56. I'm pretty sure this is the answer.

Answer:
x = 12
Step-by-step explanation:
This is a multi-step equation.

Sofia leans a 28-foot ladder against a wall so that it forms an angle of 67° with the ground. How high up the wall does the ladder reach? Round your answer to the nearest hundredth of a foot if necessary.
Using the slope concept, it is found that the ladder reaches a height of 65.96 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change.
It's also the tangent of the angle of depression.
In this problem:
The vertical change is the height that we want to find.The horizontal change is the ladder of 28 feet.The angle is of 67º.Hence:
