Answer: 66 degrees for 1st angle
52 degrees for 2nd angle
62 degrees for 3rd angle
Step-by-step explanation:
3x+(x + 30)+(x + 40)=180
3x+x+30+x+40=180
3x+x+x+30+40=180
5x+70=180
5x=110
x=22
3x=
3(22)=66 degrees for 1st angle
x+30=
22+30=52 degrees for 2nd angle
x+40=
22+40=62 degrees for 3rd angle
Answer:
3x=66
x+30=52
x+40=62
66,42,62
Step-by-step explanation:
(3x)+(x+30)+(x+40)=180
5x+70=180
5x=110
x=22
3x=66
x+30=52
x+40=62
