Answer:

<h2>They are supplementary.</h2>

Step-by-step explanation:

As you can observe in the image attached, angle 1 and 5 are congruent because they are corresponding angles which are always congruent.

However, notice that inside the parallels there are several triangles, there we have alternate interior angles and same-side interior angles.

It's importatnt to know that alternate interior angles are always congruent like angles 4 and 5 or 3 and 6.

But, angles 3 and 5 are same-side interior angles, which always sum 180°, that is, they are supplementary.

$\angle 3 + \angle 5 = 180\°$

Therefore, the correct answer is the last choice.

Turn 0.272727... into a fraction

kherson [118]

Answer:

0.272727… = 27/99

Step-by-step explanation:

(since 27 is the repeating part of the decimal and it contains 2 digits). We can reduce this fraction (a process that we'll talk more about in a future article) by noticing that we can divide both the numerator and denominator by 9 to get 0.272727… = 27/99 = 3/11.

Find the conjugate and product of<br><br>2-i5

WITCHER [35]

Answer: $2+i5,\ 29$

Step-by-step explanation:

Given

Complex number is $2-i5$

Its conjugate is obtained by changing the sign of the original number i.e. $2+i5$

The product of the two numbers is

$\Rightarrow (2-i5)(2+i5)=2^2-(5i)^2\quad \quad [(x+y)(x-y)=x^2-y^2]\\\\\Rightarrow (2-i5)(2+i5)=4-25i^2\\\\\Rightarrow (2-i5)(2+i5)=4+25=29$

1. The three salespeople for a local advertising firm are Sara, Kenny, and Leila. Sara sold $3350 in ads, Kenny sold $1368, and

Dominik [7]

Answer:

$\text{Fraction of Sara sold }= \dfrac{1675}{2587}$

$\text{Fraction of Kenny sold }= \dfrac{684}{2587}$

$\text{Fraction of Leila sold }= \dfrac{228}{2587}$

Step-by-step explanation:

The three salespeople for a local advertising firm are sara, Kenny and Leila.

Sara sold total ads = $3350

Kenny sold total ads = $1368

Leila sold total ads = $456

First we calculate total sale of all three = 3350 + 1368 + 456 = $5174

We need to find fraction of total sale with each person sell.

$\text{Fraction of Sara sold }=\dfrac{\text{Sara total sold}}{\text{Total sale by all three}}$

$\text{Fraction of Sara sold }=\dfrac{3350}{5174}\Rightarrow\dfrac{1675}{2587}\approx 64.75\%$

$\text{Fraction of Kenny sold }=\dfrac{\text{Kenny total sold}}{\text{Total sale by all three}}$

$\text{Fraction of Kenny sold }=\dfrac{1368}{5174}\Rightarrow\dfrac{684}{2587}\approx 26.45\%$

$\text{Fraction of Leila sold }=\dfrac{\text{Leila total sold}}{\text{Total sale by all three}}$

$\text{Fraction of Leila sold }=\dfrac{456}{5174}\Rightarrow\dfrac{228}{2587}\approx 8.8\%$
