Question

an angle is 200 more than three times the given angle. if the two angles are supplementary then the angles are
a- 20 and 160
b-40 and 140
c-60 and 120
d- 70 and 110

Answer 1

Answer:

40 nd 140

Step-by-step explanation:

let one angle be =x

other angle =3x+20

x+3x+20=180°

4x+20=180°

4x=180°-20

4x=160°

x=40

other angle= 3x+20

3×40+20

140

Answer 2

Although a part of your question is missing, you might be referring to this question:

An angle is 20° more than three times the given angle. If the two angles are supplementary then the angles are?

Given: An angle is 20° more than three times the given angle. The two angles are supplementary.

To find: The angles

Solution: Supplementary angles are a pair of angles whose sum is equal to 180°.

Let the given angle be x.

Since the other angle is 20° more than three times the given angle,

The other angle= 3x+20°

Since both of them are supplementary angles, therefore:

x + (3x+20°) = 180°

=> 4x + 20° = 180

=> 4x = 180-20

=> 4x = 160

=> x = 160/4

=> x = 40°

The other angle= 3x+20°

= 3× 40° +20°

= 140°

Therefore, the angles are 40° and 140°.
