Answer 1

Answer:

Here is ur answer dude

1. 7.2. 6.5. by division method

2. one exterior angle of a regular 9 side polygon is 40 degree

one exterior angle of a regular 15 side polygon is 24 degree

3. if we subtract 53 from 1989 we get perfect square and and square root of perfect sq will be 44

4. Adjacent angle of a parallelogram is = 180

let each angle be x

3x +2x= 180

5x = 180

x = 180 / 5

x= 36

first angle = 36*3 = 180

second angle 36*2 = 72

5. By Pythagoras theourm

Ac sq = AB sq + BC sq

Ac aq = 6 sq + 8 sq

AC sq = 36 + 64

AC sq = 100 cm

AC sq = 10 cm

2

AC sq = AB sq + Bc sq

AB sq = AC sq - Bc sq

AB sq = 13 sq - 5 sq

AB sq = 169 - 25

AB sq =. 144 cm

AB = 12 cm
