Question

pls answer this one an angle is 2/3of it's supplement with explination​

Answer 1

Step-by-step explanation:

an supplementary angle is equal to 180°

so, 2/3 of 180

=

$\frac{2}{3} \times 180 \\ \\ = 2 \times 60 \\ \\ = 120$

so the angle is 120°

Answer 2

Answer:

72°

Step-by-step explanation:

let that angle be x

x = 2/3 rd of its supplement angle

x = 2/3 *(180- x)

x = 120 - 2x/3

5x = 360 => x = 72°

required angle = 72°
