AE = 1/2 * AC

AC = DB so

AE = 1/2 * DB

therefore

4x - 12 = 1/2(7x - 18)

4x - 12 = 3.5x - 9

0.5x = 3

x = 6 answer

In this question, AE is the length of half of one diagonal in the rectangle. DB is the length of the other diagonal. 2(4x-12) would be the total length of the other diagonal, AC. You can set 2(4x-12) equal to 7x-18 and solve for x.

2(4x-12)=7x-18

8x-24=7x-18

x-24=-18

x=6

In circle A shown below, m is 67° and m is 74°. <br> What is m∡FDE?
deff fn [24]
Use this theorem: in a circle, the measure of an angle formed by two chords that intersect inside the circle is half the sum of the arcs formed by the chords.

In this case the sum of the arcs formed by the chords is 67° + 74° = 141 °, then the half is 141° / 2 = 70.5°.

Answer: 70.5°

Can someone please help me with these? I'm giving 100 points so please.
Cerrena [4.2K]

Answer:

1. -2\frac{9}{12}

2. 10\frac{1}{8}

3. 3

4. -1 > x

Step-by-step explanation:

1.

-\frac{33}{12}  \\12 * 2 = 24\\33 - 24 = 9\\-2\frac{9}{12}

2.

10 \frac{1}{8} / \frac{3}{4} = 13\frac{1}{2} \\13\frac{1}{2} + \frac{1}{2} = 14

3. All share the factor of 3

4. Open circle is used for < (less than) or > (greater than). Shade to the right for > or ≥.

I hope this helps! May I please have brainliest? :)

Parallelogram PQRS is shown. m/S=(3x), m/R=120, and m/Q=(2y). Find the value of y.A.
fomenos

Option B. From the parallelogram PQRS the value of y is given to be 30

<h3>How to solve for the value of y from the parallelogram</h3>

In order to get the value of y we have to use the formula

2y + 120 = 80

where the value 120 is the angle that is stated as 120 from the question

2y = 180 - 120

2y = 60

y = 60 / 2

y = 30

Hence the value of y = 30

We can go ahead to get the value of x as well

3x + 120 = 180

take the like terms

3x = 180 - 120

3x = 60

divide through by 3 to get x

60 / 3 = x

20 = x
