Each vertical angle corresponding to 40°,50° and 60° will be acute....so that's 6

 

In addition...the angle between the 50° angle and the horizontal line will have measure of 180 - 50 - 60 - 40 = 30°

And its corresponding vertical angle will also have the same measure...so...

 

All 8 angles formed by the 4 intersecting lines will be acute will be acute

Oops Sorry. That was a typo. I ment to say  "Why is the answer not 8?" I originally said 8 but it said I was wrong...

It looks like Lightning does strike twice in the same place.
