Please help in solving this paper

Answer 1

Answer:

Step-by-step explanation:

Number 10...

A quadrilatersl has a total of 360degrees hence add the ratios and equate to 360.

1+3+7+9=20

So 20=360degrees

Then equate each ratio.

20=360

1 =?

3=?

7=?

9=?

Cross multiply to get each.use the same knowledge for number 27 where two of the angles are 65.a quadrilatersl has 360 so 65 + 65=130.then 360-130=230

230 divide by two because the remaining angles are equal .

230÷2=115 each

Number 13....

1/5of a number should give 60

1/5 of x=60

Then take 60÷1/5

Which changes to 60 ×5/1=300
