Answer:
Explanation:
First, they want you to recall that in a right triangle, that you know the angle y, because you know two of the angles already. and you know the total is 180° around a triangle. There is a lot you're supposed to remember. Anyway,
180 = y + 62+90
180-62-90 = y
28 = y
see??
z = the same length, as triangle IHK on the same segment
z= 1
