Question

Please Answer with explanation​

Answer 1

Answer:

1) Sum of two complimentary angle is 180°

let the angle be X then if they are in the ratio 2:7

their sum will be

2x + 7x= 180

9x= 180

x=20

so the angles are

2×20 = 40

2×70 = 140

2) (i) angle ROS

= angle POR+angle ROS+angleSOQ=180°

(linear pair)

= 65+angle ROS+14=180

angle ROS=180-74

= 106

(ii) angle POS = angle POR+angle ROS

= 65+106

= 171

3) Let the share be 1

P get 2/5

Q get 3/10

making the denominator same

P gets 4/10

Q gets 3/10

that mean

P's share = 90,000 × 4/10 = 32000

Q's share = 90,000 × 3/10 = 27000

then R's share is

90,000-32000-27000 = 31000
