Answer:
x=75
Step-by-step explanation:
A triangle is 180° in total and the equation was (2x+30)° if you subtract 30 from 180 you get 150 if you divide that by 2 you get 75.
Answer: 2(75) + 30° =180°
x = 35
x = 35, because first you have to add all your like factors. Then you'd get 2x + 110 = 180, afterwards you'd subtract 110 from both sides. Then divide 2 on both sides. Leaving you with x = 35.
