Question

I know it is simple, but my mind is overloaded right now. Help would be appreciated

Answer 1

OK.  Don't blow a fuse.

Remember:  The interior angles of every triangle always add up to 180 degrees.

So ' x ' is whatever you need to add to (60+70) to reach 180.

     60 + 70 = 130 .

Make up the difference between 130 and 180, and you'll have ' x '.
