Answer:
110°
Step-by-step explanation:
128°+40°+82°+x°= 360°
so 250°+x°=360°
x°=360°-250°
x°=110°
Answer:
Factor 3x^2-17x-20, and you get (x + 1)(3 x - 20)
x = 17/6 + sqrt(1729)/6, x = 17/6 - sqrt(1729)/6
Step-by-step explanation:
Factor 3x^2-17x-20, and you get (x + 1)(3 x - 20)
When 3x^2-17x-20 is equal 100
3x^2-17x-20=100
Subtract both sides by 100
3x^2-17x-120=0
Use the quadratic formula
x = 17/6 + sqrt(1729)/6, x = 17/6 - sqrt(1729)/6
