Question

find the Supplementary angle of a small angle that is 1 /8th of its big angle​

Answer 1

Answer:

Let the big angle be 'x'

According to the data,

Smaller angle = x/8

We know that,

Sum of angles = 180°

x + x/8 = 180

9x/8 = 180

x = 160°

Smaller angle = x/8 = 20°

I hope this helps you...

Have a nice day...

Answer 2

Step-by-step explanation:

Let the big angle be x.

Then small angle = 1x/8

Sum of supplementary angles = 180 degrees

Therefore,

x + 1x/8 = 180

9x/8 = 180

x = 160 degrees
