Answer:
9.32
10.116
Explanation:
each corner is a right corner so were going to subtract 58 from 90 because all right corners are 90 degrees
90-58=32 answer A 32
after that we know that all triangles have to equal 180 so now we subtract
180-58=122 122-58=64
we subtract 58 two times because we have 2 of the same angles
next we know that the smaller angle is 32 so now we subtract again
180-32=148 148-32=116 so y is 116
