Question

. If there are four angles on a straight line and they are in the ratio 1 : 2 : 3 : 4, what is the difference of the largest and smallest angle of the four? *



54°

36°

48°

56°​

Answer 1

Answer:

54° is the difference.

Explanation:

Let the angles - x + 2x + 3x + 4x.

Straight angle measure= 180°

Put them equal to 180°.

Then, x= 18°

Smallest angle= 18°

Largest angle= (18×4)°

Difference= 72°- 18° = 54°
