Question is in the photo

y=45 degrees and x=45 degrees

Step-by-step explanation:

yzx is a triangle

m<z= 90 degrees

sum of interior angles in a triangle is 180 - 90 (m<z) = 90

therefore y+x=90

and y=x

therefore;

y=45 degrees and x=45 degrees

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
