Answer 1

Answer:

Here, angle 3 will be equal to angle 5 (because EF || CD)

Thus, /3=/5=55°

Now, we'll take AB and ED as a single line as these line are perpendicular to each other..

Then /1+/2+/5=180°

60°+55°+/2=180°

/2=180°-115°

/2=65°

Now..

For finding /4,

/4+/3=180°

/4=180°-55°

/4=125°
