Answer:

Step-by-step explanation:

number of side = n =7

Sum of all the angles of  given polygon = (n -2)*180 = 5 *180 = 900

x + 140 +133 +145 + 117 + 119 + 125 = 900

                                             x +  779 = 900

                                                    x     = 900 - 779

x = 121

2476 adults watch a cricket match. The ratio men : women is 3 : 1 How many more men than women watch the match?
poizon [28]

he ratio of 3:1 involves 4 units. 3 men +1 woman.

Find how many people each unit represents:

    4units        2476 people

Therefore each unit represents 2476/4 = 619 people per unit

Now, take the ratio, and multiply up:

3:1  =>  3619:1619   =>   1857:619    You check this is right by adding the two fractions:

1857 men + 619 women = 2476 people therefore, we are correct

The number of men more than women = Number of men - Number of women

                                                       = 1857-619 = 1238 and that is your answer
