Proposition:Let the diagonals AC and BD of the Parallelogram ABCD intercept at E. It is required to prove AE=CE and DE=BE
Proof:1)The lines AD and BC are parallel and AC their transversal therefore,
[tex] \displaystyle \angle DAC = \angle ACB \\ \ \qquad [\text{ alternate angles theorem}][/tex]
2)The lines AB and DC are parallel and BD their transversal therefore,
[tex] \displaystyle \angle BD C= \angle ABD \\ \ \qquad [\text{ alternate angles theorem}][/tex]
3)now in triangle ∆AEB and ∆CED
[tex] \displaystyle \angle EAD=\angle ECB[/tex][tex]\angle EDA=\angle EBC[/tex][tex] \displaystyle AD=BC[/tex]therefore,
[tex] \displaystyle \Delta AEB \cong \Delta CED [/tex]
hence,
AE=CEDE=BEProven

A choir teacher is dividing 12 sopranos and 9 altos into singing groups. He wants each group to have the same combination of sopranos and altos, with no singers left over. What is the greatest number of groups he can make?
Answers
Answer:
3 groups
Step-by-step explanation:
Sopranos = 12
Altos = 9
Find the highest common factor of 12 and 9
12 = 1, 2, 3, 4, 6, 12
9 = 1, 3, 9
The highest common factor of 12 and 9 is 3
Therefore, the choir teacher can only have 3 groups
12 sopranos / 3 groups
= 4 sopranos per group
9 Altos / 3 groups
= 3 altos per group
Each of the 3 groups Will have 4 sopranos and 3 altos each
Use the table to write a linear function that relates y to x.
Answers
Answer:
y=(3/2)x+5
Step-by-step explanation:
Sketch it out real quick on a piece of paper.
As you can tell from the table, for every 3 units along the x axis, 2 units upwards are taken along the y axis.
This makes the slope of the equation (3/2)x or (1 1/2)x
The y-intercept is at y=5 because (on the table), when x=0, y=5.
This makes the equation in point-slope form y=(3/2)x+5

[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = [tex]5\sqrt{3}[/tex]
90* = 10

Joe needs to put a fence around the perimeter of a circular pool. The radius of the pool is 14 feet. How much fencing will Joe need to surround the entire pool? Leave your answer in terms of π.
Answers
Answer:
28[tex]\pi[/tex] feet
Step-by-step explanation:
Find how much fencing he will need by finding the pool's circumference:
Use the circumference formula, C = 2[tex]\pi[/tex]r
C = 2[tex]\pi[/tex]r
C = 2[tex]\pi[/tex](14)
C = 28[tex]\pi[/tex]
So, Joe will need 28[tex]\pi[/tex] feet of fencing
