You don't need to answer the first one because i know i'm right on it, just answer 2 and 3.

ok, so you can find angle 4 using the vertical angles theorem, angle 4 is 52 degrees. That was number 2

Number 3. if angle 1 is 50 then using vertical angles will show that angle 4 is also 50 degrees, angle 4 and 5 are complementary meaning that when they are added it is 90 degrees. so subtract 50 from 90 and you are left with 40. Angle 5 is 40 degrees.

so number 2 is 53

number 3 is 40

hope this helps
