Answers

Answer 1

Answer: 3 is a irregular pentagon (pentagon, penta=five, regular means all equal sides and angles)

4 is , I can't see the bottom, if there are only 3 lines, then the figure is a triangle
if ther are 4 sides then it is either, (if the sides are not parrelel then the figure is a quadrilateral) (if 2 sides are parrelell then it is a trapizoid or trapezium)

7 is a quadrilateral because it has 4 sides and cannot be classified further because it doesn't have parralell sides

Answer 2

Answer: 3 is a pentagon - it has five sides.
7 is a quadrilateral - it has four sides.
I cannot see what number 4 is, as you have cut it off with the picture.

What is repeating decimal?

A repeating decimal is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending.

According to the given question.

We have to find a repeating decimal which is less than 0.2.

And if we write it in a fractional form, its denominator will less than 10.

So, if we take a fraction or rational number $(1)/(9)$ . Here, the denominator is less than 10 ( 9<10).

And when we evaluate $(1)/(9)$ we will get a repeating decimal 0.111111111.....

Hence, $(1)/(9)$ could be one fraction whose repeating decimal is less than 0.2 and denominator is less than 10.

Answer:

1. a= 7, A = 49 degrees

Side A = 7 , Side B = 24, Side C = 25

A= 49 degrees, C = 90 degrees , B=41

2. A= 4, B = 6.9, C=8

A= 22 degrees, B = 68, C= 90

3. A= 7, B = 14.4, C=16

A= 45 , B=45 , C=90
