Suppose ABCD is a parallelogram. If AB = 9x + 2, CD = 12x - 4, BC = x + 7, determine the length of AD.

Need help asap

Answers

Answer 1
Answer:  9 units

======================================================

Explanation:

For any parallelogram, the opposite sides are parallel and are the same length.

AB = CD

9x+2 = 12x-4

2+4 = 12x-9x

6 = 3x

x = 6/3

x = 2

Which leads to

AB = 9x+2 = 9(2)+2 = 20CD = 12x-4 = 12(2)-4 = 20BC = x+7 = 2+7 = 9

Side AD is opposite BC, so AD = BC = 9

Answers

Answer:

y is 12 degrees

x is 30 degrees

Step-by-step explanation:

If angle ABC is equal to angle MNC, that means 5y equals to 60 degrees. 60 divided by 5 equals 12. So, y equals 12 degrees

2x and 4x equals 180 degrees. So, 180 divided by 6 equals to 30. So x equals 30 degrees

Answer:

x = 30, y = 12

Step-by-step explanation:

2 similar equilateral triangles, each corner is 60 degrees.

2x = 60 degrees

divide by 2

x = 30 degrees

5y = 60 degrees

divide by 5

y = 12 degrees

This can be verified by checking 4x + 2x which gives you 180 degrees forming that straight line angle.

Find the missing angle.

Answers

Answer:

32 degrees

Step-by-step explanation:

The angle supplementary with the 122 degree angle measures 180-122=58 degrees.

So, the triangle has interior angles of f, 90, and 58 degres.

Since the angles in a triangle add to 180 degrees, f+180-90-58=32 degrees

a

b
$153.50
c

Answers

Answer: B

Step-by-step explanation:

In 6 months she will have to pay $921

In 1 month she has to pay [tex]\frac{921}{6}[/tex] = $153.50

Each month, Yvette has to pay $153.50 in order to pay off the tires before she will have to pay interest

Therefore, B is the correct answer

You’re answer is B . $153.50 dollars a month because $921 divided by 6 months is $153.50 and there’s 0% interest rate so it don’t change the problem at all it’s still going to be B . $153.50
