Answer:
Angle 1: 55
Angle 2: 110
Angle 3: 15
Step-by-step explanation:
Angle 1: x
Angle 2: 2x
Angle 3: x-40
The total degrees for all the angles in a triangle add up to 180, so we now have the equation x+2x+x-40=180. From here we solve to get 55 degrees for x, so angle 1 is 40 degrees, angle 2 is 110 (2 times 40) and the third angle is 15 (55-40).

Answer:
Graph 4
Step-by-step explanation:
Parallel lines have no solution to the system of equation. Graph 4 is a set of parallel lines, so they will never intersect.
Answer:
m∠5= 130°
Explanation:
If lines A and B are parallel we can assume that the angles in the same locations are equal
Answer:
A) 27
B) 1/9
C) 1/9
Step-by-step explanation:
A) 3×3×3 = 27 outcomes
B) (3×2)/27 = 1/9
C) first one is a purple, probability of next 2 being orange is:
1/3 × 1/3 = 1/9
