Answer 1

$\huge\boxed{\mathfrak{\red{\fcolorbox{red}{pink}{ Answer}}}}$

1) 8 angles

2) 1,3,5,7,9.

Their mean (average)= = 25/5 =5.

answer is 5

3) let Aman 's age be x

his mother's age 7x

sum of age = 48

A/Q

x +7x = 48

8x = 48

x = 48/8

$\therefore \: x = 6 \: { \tt \red{ans}}$

4). In this solution, the one supplement angle is taken by X and twice of supplement angle is 2X. So that it remains two supplement that is measured by angle at 180 degree and then consider it as X x+2x=180°, 3x=180°, x=180÷3=60°, 2×60=120°. Therefore, two supplement angles takes place by 180 degree.
