Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>30</u></em></h2>
Step-by-step explanation:
<em><u>According</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>figure</u></em><em><u>, </u></em>
54° + 3x+36° = 180° <em>[</em><em>Linear</em><em> </em><em>pair</em><em>]</em>
=> 3x + 90 = 180
=> 3x = 180 - 90
=> 3x = 90

=> <em><u>x = 30 (Ans)</u></em>
So for every two girls, there's four boys. There are twice as many boys than girls, so the number of girls • 2 = your answer.
51 • 2 = 102
Multiply each of the numbers by a ten to a power that they both become whole numbers.
0.67 *

= 67
0.3 *

= 30
Divide as usual.
67 / 30 = 2

So, the answer is 2 1/3.
