Question

An angle is 2/3 of its supplement. Then what is magnitude.

According to 7th class.​

Answer 1

Step-by-step explanation:

ANSWER

⇒ Let one angle be x.

⇒ Then, other angle will be 2/3x

According to the question,

x+ (2/3)x =180°

• (3x+2x)/3 =180°

•5x/3 =180°

•5x=540°

∴ x=108°

∴ ( 2/3)x = 2/3×108 ° =72 °

∴ Magnitudes are 108 °

and 72°
