Answer:
∠y = 62.5°
∠x = 27.5°
Step-by-step explanation:
z is right angle. ∠z = 90°
∠x = ∠y - 35
∠x + ∠y + ∠z = 180 {Angle sum property of triangle}
y - 35 + y + 90 = 180
y + y - 35 + 90 = 180 {Combine like terms}
2y + 55 = 180
2y = 180 -55 {Subtract 55 from both sides}
2y = 125 {Divide both sides by 2}
y = 125 /2
∠y = 62.5°
∠x = 62.5 - 35 = 27.5°
Answer:
={6,7,8,9,10}.
Step-by-step explanation:
We have an empty set: M={} and the set N={6,7,8,9,10}.
The union of these two sets are elements in M or N or both.
Since the M is a null set, 
Therefore:
={6,7,8,9,10}.
The union for the given sets is {6,7,8,9,10}.

Step-by-step explanation:
All angles of a triangle equal up to 180
6x+4x-3+x+7=180
11x+4=180
11x=176
x=16
