If we know just two sides of a triangle, we can find<span> the </span>measure<span> of the</span>angles<span>. Step 1: Choose which trig </span>ratio<span> to use. We need to determine how the two sides we know the length of are related to </span>angle<span> A. The 4 in. side is adjacent to A and the 7 in.</span>
The answer to this question is 2
X+y=7
x•y=-18
x+y=7
x=7-y
x•y=-18
(7-y)•y=-18
7y-y^2=-18
-y^2+7y+18=0
Y^2-7y-18=0
(y-9)(y+2)=0
y is either 9 or -2
x+y=7
x=7-y
X=7-9
X=-2
X•y=-18
9•(-2)=-18
-18=-18
There you go, y is 9 and x is -2
Answer:
I think you are correct
