This is what I found

Step-by-step explanation: <em>If you look at the figure, the angle marked red is equal to 70° because vertical angles are equal. So, that also means that the opposite angle 2 is also 70°. So, the first equation is:</em>

<em />

<em>70 = 5x + y</em>

<em />

<em>Next, the green angle as marked is equal to</em>

<em>Green angle = 180 - 70 = 110</em>

<em>Being vertical angles, angle 1 is then equal to 110°. So,the second equation is</em>

<em />

<em>110 = 5x + 3y</em>

<em />

<em>Subtract the two equations:</em>

<em />

<em>    5x + y = 70</em>

<em> -  5x + 3y = 110</em>

<em>________________</em>

<em>           -3y = -40</em>

<em>              y = -40/-3 = 13.33°</em>

<em />

<em>Substituting y to either one of the equations,</em>

<em>5x + 13.33 = 70</em>

<em>Solving for x, </em>

<em>x = 11.33°</em>

<em />

Please help thank you

Answer:

a = 4

b = 11

Step-by-step explanation:

To convert the recurring decimals into fraction we will follow the following process.

Given recurring decimal is 0.36363636....

Let x = 0.363636......... (1)

Multiply this decimal with 100.

100x = 36.36363636...........(2)

Now subtract expression (1) from expression (2)

100x = 36.363636.......

<u>      x =   0.363636.......</u>

99x = 36

x = \frac{36}{99}

x = \frac{4}{11}

Since, x=\frac{a}{b}=\frac{4}{11}

a = 4 and b = 11 will be the answer.

1                     1                       1/24 =  0.042 = 4.2%

3                      2                       2/24 = 0.083  = 8.3%

4                       1                         1/24 = 0.042  = 4.2%

5                       1                          1/24 = 0.042  = 4.2%

6                       1                           1/24 = 0.042 = 4.2%

7                        2                         2/24 = 0.083 = 8.3%

8                        1                          1/24 = 0.042   = 4.2%

9                       2                           2/24 = 0.083  = 8.3%

10                       6                           6/24 = 0.25   = 25%

11                        1                            1/24 = 0.042 = 4.2%

12                           2                           2/24 = 0.083 = 8.3%

13                         2                           2/24 = 0.083 = 8.3%

14                         2                           2/24 = 0.083  = 8.3 %

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

                              24                                         1
