You can put this solution on YOUR website! In any triangle, the sum of all angles is 180 degrees. Since in a
right triangle, one angle is always 90 degrees, that leaves 180-90=90
degrees for the sum of two other sharp angles. So, since one angle is
given as 74+9 degrees, the other sharp angle is 90-74+9, or
16 degrees.
So, the answer is that the angles of this straight triangle are 90,
74+9, and 16 degrees.

You can put this solution on YOUR website! This is what the expression would look like.
if x=7 and y=4, then xy+9 would be (7)(4)+9 which would be 28+9 which would be 37.
