The three angles of a triangle add up to 180.
Since you know that two angles add up to 80, you know that the third angle is 100.
Answer: 1/2
Step-by-step explanation:
30x + 18 = 35-4x
collecting like terms
30x + 4x = 35-18
34x = 17
divide both sides by 34
34x/34 = 17/34
x = 1/2

Step-by-step explanation:
Answer:
Undefined or Infinity
Step-by-step explanation:
(x1,y1)=(-11,8)
(x2,y2)=(-11,-17)
Slope = (y2-y1)/(x2-x1)
= (-17-8)/(-11-(-11))
= -25/0
= Undefined
