we can clearly see that 4c° + 90° +4c° = 180°
as the sum of all the angles at a point on straight line is 180°
8c° = 90°
c° = 11.25°
also,
16c° = 180°
c° = 11.25°(answer)

himanshi98:
its solved
if any doubt you can asl??
thanks can yu please tell me why we had not added 16c
ask??
yes why we have nt added 16 c
because 16c will itself be equal to 180° as it is clear from the figure that it is on a straight line
thanks can yu do one more like that i have posted it
yaa sure
yu can go to my profile and the can yu answer the last question of findin the value
please

Answer:
Given that, all the four angles given form 360°.
Hence, 16c° + 90° + 4c° + 4c° = 360°.
Adding the like terms in the equation,
➸ 24c° + 90° = 360°
➸ 24c° = 360 - 90
➸ 24c° = 270°
➸ c° = 270/24
➸ c° = 11.25
Hence, the angles =
- 90°
- 16c° = 16*11.25 = 180°
- 4c° = 4*11.25 = 45°
- 4c° = 45°
______________
- The pair of angles forming 90 degree are called complementary angles.
- The pair of angles forming 180 degree are called supplementary angle.
- A straight line forms 180 degrees.
