Hey, the first one with W is = so a triangle =180 degrees. And the number you are given is 64 degrees, take note that our 1st triangle has a right angle triangle which is 90 degrees. So now we have 64 + 90 degrees which is 154 degrees , NB OUR ANGLE HAS TO EQUAL 180. So what we will do is say 180 - 154 = the answer for W. I’m unsure of the second one though
