Sum of Angles Find the value of x and the measure of every angle. It is Geometry

Mathematics

Helga [31]3 years ago

Answer:

If the sum of a triangle equals 180 degrees we’ll go off of that by doing this.

(7x+8)+(5x+2)+(7x-1)=180
7x+8+5x+2+7x-1=180
19x+9=180
19x=180-9
19x=171
19x/19=171/19
x=9

With that let’s find each angle,

I’ll just label them A, B, C.

A: (7x+8)
7(9)+8
63+8=71

B: (7x-1)
7(9)-1
63-1=62

C: (5x+2)
5(9)+2
45+2=47

71+62+47=180

How to write repeating decimals as fractions
nignag [31]

Answer:

You take the repeating group of digits and divide it by the same number of digits but formed only by 9s.

Step-by-step explanation:

Let's say you have 0.111111111111...., your repeating pattern is 1, that consists of one digit (1).  You take that digit and you divide it by 9:

1/9 is the fraction equivalent to 0.111111111111111...

Let's say you have 0.12121212121212...., the repeating pattern is 12, that consists of 2 digits (12).  You take those 2 digits and divide them by 99:

12/99 is the fraction equivalent to 0.12121212121212...

which can be reduced to 4/33

If you have 0.363363363363..., your repeating pattern is 363, which is 3 digits, so you divide 363by 999:

363/999 is the fraction equivalent to  0.363363363363...

which can be simplified to 121/333
