Answer:

because why not

Step-by-step explanation:

Answer 2

Answer:

We will cover Addition and Subtraction in one go, as they are the same method. Before we add or subtract, the rational numbers should have the same bottom number (called a Common Denominator).

Answers

Answer:

1) The value of x is:

2) The degree for angle 1 is: 59°

3) The degree for Angle 2 is: 121°

Step-by-step explanation:

First we must find x, to do that we must find out what we are given:

m<1 = (2x + 23)°

m<2 = (7x - 5)°

Now we must see if there is any info that can help us find the angles:

Angle 1 and 2 are supplementary.

The word 'supplementary' is very important as it can help us evalute how to set up our problem.

Supplementary means the sum of 2 angles that create a 180°

So our measures will = 180°

(2x + 23) + (7x - 5) = 180°

Now we must try and find the value of x:

1) Remove the parenthesis, and combine like terms:

2x + 7x + 23 - 5 = 180°

9x + 18° = 180°

     - 18° =  -18°

---------------------

9x = 162°

2) Divide both sides by 2 in order to get 'x' value by itself:

[tex]\frac{9x}{9}=\frac{162}{9}[/tex]

[tex]x=18[/tex]

Your value of x is 18.

Now you must substitue the value of x into you measures, to get your angles:

(2x + 23)°

2(18) + 23

36 + 23

= 59°

(7x - 5)°

7(18) - 5

126 - 5

= 121°

Is this statement true? Let's find out!

121° + 59° = ?

= 180°

It is true.

angle 1 is 59 and angle 2 is 121

EX: You decided to go to college but as a broke college student you couldn't pay for college (because it is expensive) so you decide to take out a student loan. For simplicity's sake let's say that you only need a $15,236.75 loan to add to the money you had saved up for college. However, the loan agency adds a 0.05 per month interest rate as soon as your 4 years of college are over. Knowing that interest adds up fast you decide to try to pay off as much loan debt as you can while still in college with your part-time job. You end up paying off $746.98 leaving you with only $14,489.77 left of the loan. The first month out of college you wind up with only $15,214.26 of college debt. Before the next month however you marry your college sweetheart and as a couple, you take on each other's debts making your grand sum for college debts $32,416.51. After five blissful years of marriage you wind up getting a divorce but because finances have been jumbled (real-world ish) you decide just to divide the $12,758.36 debt from college evenly between the two of you.

Subtraction:

15,236.75-746.98 = 14,489.77

Multiplication:

14,489.77x.05 = 15,214.26

Addition:

32,416.51 = 15,214.26+17,202.25

Division:

12,758.36/2 = 6,379.18

Which of the following describes two triangles that are similar to one another?

Answers

We have to determine, which of the following triangle is similar to another one.

Two similar triangle are always congruent. Two figures are similar if they have the same shape and size.

Two triangles are similar if their corresponding sides are proportional. Two polygons are similar if their corresponding side are proportional.

If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Both triangles are similar by SSS theorem, because all three pairs are in proportion,

To calculate the proportion of sides,

Triangle 1; m1 = 67, m2 = 15

Triangle 2 ; m1 = 15 , m2 = 95

[tex]\dfrac{67}{15}= \dfrac{15}{95}[/tex]

Thus the angles are not proportion then the triangle are not similar.

Triangle 1; m1 = 24, m2 = 101

Triangle 2 ; m1 = 65, m2 = 101

[tex]\dfrac{24}{65}= \dfrac{101}{101}[/tex]

Thus the angles are not proportion then the triangle are not similar.

Triangle 1; m1 = 45, m2 = 80

Triangle 2 ; m1 = 59 , m2 = 45

[tex]\dfrac{45}{59}= \dfrac{80}{45}[/tex]

Thus the angles are not proportion then the triangle are not similar.

Triangle 1; m1 = 71, m2 = 32

Triangle 2 ; m1 = 71 , m2 =77

[tex]\dfrac{71}{71}= \dfrac{32}{77}[/tex]

Thus the angles are in same proportion then the triangle are similar.
