How to identify pairs of angles
Answer:
When a pair of parallel lines is cut with another line, known as an intersecting transversal, it creates pairs of angles with special properties.
Step-by-step explanation:
CORRESPONDING ANGLES are equal
<1 and <5 <2 and <6 <4 and <8 <3 and <7
ALTERNATE INTERIOR ANGLES are equal
<3 and <5 <2 and <8
ALTERNATE EXTERIOR ANGLES are equal
<1 and <7 <4 and <6
VERTICALLY OPPOSITE ANGLES are equal
<5 and <7 <6 and <8 <1 and <3 <2 and <4
COINTERIOR ANGLES are supplementary, meaning adding their measurements together will give you 180°
<2 and <5 <3 and <8

How much is there in the second pile?
Answer:
plz mark me as brainliest ❤️
12 coins are there in the second pile, when number of coins in two piles are in the ratio of 3 : 8 and the coins in the first pile are 50ps and coins in the second pile are 20ps.
The number of coins in two piles are in the ratio of 3 : 8.
The coins in the first pile are 50ps
The coins in the second pile are 20ps
There is £4.50 in the first pile.
We need to how much in the second pile
What is ratio?A relationship between two things when it is expressed in amounts is called ratio
By Given data,
The number of coins in two piles are in the ratio of 3 : 8.
The coins in the first pile are 50ps
The coins in the second pile are 20ps
There is £4.50 in the first pile.
We need to find how much in the second pile.
(4.5*8)/3
Calculate the product and divide it by 3
36/3
The division of 36/3 is 12.
So if there is £4.50 in the first pile. then 12 are there in the second pile

Answer:
1/9
Step-by-step explanation:
Let's take a pizza, for example. Let's say it has 9 slices in total, and you eat only one slice. That leaves 8 remaining. Therefore the majority of the original pizza is still remaining, because you only ate 1 slice. If you ate 1/2 tho, you would have eaten 4 & 1/2 slices, and so on and so forth for the rest of the fractions, making 1/9 the smallest fraction

(5 + 6i)(5 - 6i)
Answer:
61
Step-by-step explanation:
(5 + 6i)(5 - 6i)
FOIL
first: 5*5 =25
outer: 5 *-6i = -30i
inner: 6i *5 = 30i
last: 6i * -6i = -36 i^2 =-36 (-1) = 36
Add together
25 -30i+30i+36
61
[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
[tex] \sf \: ( 5 + 6 i ) ( 5 - 6 i )[/tex]
Multiply complex numbers 5+6i and 5-6i in the same way as you multiply binomials.
[tex] \dashrightarrow \sf 5\times 5+5\times \left(-6i\right)+6i\times 5+6\left(-6\right)i^{2} [/tex]
By definition, i² is -1.
[tex] \dashrightarrow \sf 5\times 5+5\times \left(-6i\right)+6i\times 5+6\left(-6\right)\left(-1\right) [/tex]
Do the multiplications.
[tex] \dashrightarrow \sf \: 25-30i+30i+36 [/tex]
Now cancel -30i & +30i
[tex]\dashrightarrow \sf \: 25 \: \bcancel{- 30i} \: + \: \bcancel{30i}+36 [/tex]
Now the equation becomes

I hope I helped you^_^
These triangles are congruent by the triangle postulate ASA.
Option A is the correct answer.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
From the two similar triangles.
There are two corresponding angles and one corresponding side that are equal.
We see that,
The side is between the two angles.
So,
ASA = Angle - Side - Angle
This postulate is used.
Thus,

The rhumbas has a perimeter or 16 and height of 3 what is the area ?
Answer:
[tex]A=\frac{3\sqrt{55}}{2}[/tex]
Step-by-step explanation:
For a height h, a perimeter P, and an area A, use the following formula:
[tex]A=\frac{1}{4}h\sqrt{P^{2}-4h^{2} }[/tex]
Next, replace the variables with the given values:
[tex]A=\frac{1}{4}(3)\sqrt{(16)^{2}-4(3)^{2} }[/tex]
Solve the inside of the square root:
[tex]A=\frac{1}{4}(3)\sqrt{256-36}\\A=\frac{1}{4}(3)\sqrt{220}[/tex]
Multiply outside of the square root:
[tex]A=\frac{3}{4}\sqrt{220}\\[/tex]
Simplify the square root:
[tex]A=(\frac{3}{4})2\sqrt{55}\\[/tex]
Multiply outside of the square root once more:
[tex]A=\frac{3}{2}\sqrt{55}\\[/tex]
Simplify:
[tex]A=\frac{3\sqrt{55}}{2}[/tex], or ≈ 11.12429773
