Answer 2

Given:

• Difference between supplementary angles is 30°.

Need to find:

• each angle ?

⠀⠀⠀⠀⠀⠀⠀

Solution:

Let, the supplementary angle be "x".

And, the other angle be (180 - x).

According to the question,

➜ x - (180 - x) = 30

➜ x - 180 + x = 30

➜ 2x = 30 + 180

➜ 2x = 210

➜ x = 210/2

➜ x = 105

Therefore,

• One angle, x = 105°
• Other angle, (180 - x) = (180 - 150) = 30°
