They are -9 and 8. because since 9 times 8 is 72, you need the 9 to be negative to add to -1
So x and y are supplementary because the angle beside X is 90º so all together it’s 180º
And each side should add up to 90º
So x and y should each be 45º if I’m not mistaken, and then z is (I forgot the proper vocab term for this) right flippity across y so it should also be 45º
