Question

two angles are supplementary.one of them is 30 degree less than five times the other. find the angles.​

Answer 1

Step-by-step explanation:

let one angle is = x°

other = (5x-30)°

supplementary angles = sum of angle is 180

x+5x-30=180

6x= 210

x= 35°

second =145°

Answer 2

Answer:

The angles are 55° and 125°.

Step-by-step explanation:

Sum of the two angles= 180°

Let the length of one of the angles be x°

and the other be 5(x-30)° [Given]

ATQ,

x° + 5(x-30)° = 180°

x° + 5x°-150° = 180°

6x° - 150° = 180°

6x° = 180°+150°

6x° = 330°

x°= 330°/6

x° = 55°

The angles are=

x=55°

5(x-30)= 5(55-30)= 5×25= 125°
