Two lines p and q intersect at X at an angle of 38 degrees. Let A be a point inside the 38 degrees angle formed by p and q Let B the reflection of A through line p and Let c be the Reflection of A through line q. Find angle BAC.

If  you  can  imagine  this.....

 

BA  will  intersect  p   at an  angle of 90°  since  A  is refected  over  p  to B

And  CA   will intersect q  at 90°  since  A  is reflected over q to C

 

So  angle  BAC   =    360  - 90  -90  - 38   =  142°
