Question

please answer it ...............​

Answer 1

Answer:

answer is 75

Step-by-step explanation:

let the angle be x

(180-x)-30=x

180-30-x=x

180-30=x+x

150=2x

x=150/2

x=75

Answer 2

Answer:

70 degrees and 110 degrees

Step-by-step explanation:

supplementary angles are angles which add up to 180 degrees

so we will first form an equation

let the number be x

x + ( 2x - 30 ) = 180

x + 2x - 30 = 180

3x - 30 = 180

3x = 180 + 30

3x = 210

x = 210 / 3

x = 70 degrees

then second angle = 2x - 30 = 2 * 70 - 30 = 140- 30 = 110 degrees

hence the angles are 110 degrees and 70 degrees
