Question

. Find the magnitude of the angle which is
(i) equal to its supplementary angle,
(ii) twice its supplementary angle,
(iii) 10° less than its supplementary angle.​

Answer 1

Answer:

i)Let supplement be x 

∴Angle=2x

x+2x=180

3x=180

x=60o

Now , Supplement = 2x=2×60=120o 

ii)Let angle be 3x, then its supplementary will be x

x+3x=34x=180

x=135o

3135=45o is measure of angle.

Answer 2

Answer:

Let magnitude of circle be X

Step-by-step explanation:

Therfore, X + X = 180

2X = 180

X = 90
