Answers
Answer:
9
Step-by-step explanation:
So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines
and A to B and D to C have two arrows meaning those two lines are the same
so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9
Hopefully this wasn't too confusing
Answer:
mCD = 9
Step-by-step explanation:
Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:
AB ║ DC
BC ║ AD
Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.
This also means that because AB = 9 and AB = DC, DC = 9.
Here's a mini two-column proof:
Statements → Reasons
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
mAB = 9 → Given
AB ║ DC, BC ║ AD → Given
ABCD is a parallelogram → Definition of a Parallelogram
AB ≅ DC → Opposite sides of a parallelogram are congruent.
mAB = mDC → Definition of Congruent Segments
9 = mDC → Substitution Property of Equality
mCD = mDC → Reflexive Property of Equality
mCD = 9 → Substitution Property of Equality

Step-by-step explanation:
cost of tank tops
20 / 5 = $4 each
cost of t-shirts
35 / 5 = $7 each
7 - 4 = $3
Answer:
$3
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the cost of each product. This can be done by diving the price by the amount of each product. After finding the unit price of each product, one will subtract the cost of the tank-top from the cost of the t-shirt.
2.The unit price of a t-shirt
It is the given that 5 t-shirts cost $35. Divide the price of the shirts by the number of shirts to find the cost of each individual shirt.
35 ÷ 5 = 7
Each individual t-shirt costs $7.
3.The unit price of a tank-top
It is given that 5 tank-tops cost $20. Divide the price of the tank-tops by the number of tank-tops to fund the unit price of each tank-top.
20 ÷ 5 = 4
Each tank-top costs $4.
4.Find out how much more each shirt costs
Now subtract the price of the unit price of the tank-top from the unit price of the t-shirt.
(t-shirt) - (tank-top)
= 7 - 4
= 3
2x + 45
(Will be marked brainlist)
Answers
Answer:
x = 45°
Step-by-step explanation:
We know that (2x + 45)° and x° are adjacent angles, so they add up to 180°.
(2x + 45) + x = 180
3x + 45 = 180
3x = 180 - 45
3x = 135
x = [tex]\frac{135}{3}[/tex]
x = 45°

Pythagorean theorem and Converse; find the value of x.
Answers
Answer:
x = 12.206555
Step-by-step explanation:
10^2 + 7^2 = 149
Sqrt(149) = 12.206555 = x
x ≈ 12.2, 12
Therefore, the value of the hypotenuse [tex]x[/tex] is [tex]12[/tex].
What is the pythagorean theorem?
The Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.
Here given that,
[tex]B=7,P=10[/tex]
As we know,
[tex]H^2=B^2+P^2[/tex]
Substitute the given values in the formula is
[tex]x^2=(7)^2+(10)^2\\\\x^2=49+100\\\\x^2=149\\\\x=\sqrt{149}\\\\x=12[/tex]
Hence, the value of the [tex]x[/tex] is [tex]12[/tex].

Answers
Answer: 222cm
Step-by-step explanation:
To find the area of this composite shape you will have to split them into 2 shapes; a rectangle and a triangle.
To work out the area of the rectangle you have to do 15×12= 180
Then, to work out the area of the triangle, you use the formula base times height divided by 2.
7×12=84
84÷2=42
Then to work out the total area of both the rectangle and the triangle, you have to add the area of both.
180+42=222cm
