What’s the angle measures ?

x+(x+30)+2x=180

open bracket

x+x+30+2x=180

collect like term

2x+2x=180-30

4x=150

divide both side by 4

4x/4=150/4

x=37.5°

so the angle are 37.5°, 75° ,67.5°

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
