Answer:
y=7
Step-by-step explanation:
-6y= -27-15
-6y= -42
y=7
Since z is GREATER THAN two angles in the triangle it must be obtuse..
meaning it is GREATER THAN 90 degrees this means that the other two angles cannot equal 90 degrees they have to be less
m∠X + m∠Y < 90°
I think you will have t use theorem
Ba=Rv^2+vo^2
Ba=4^2+7^2
Ba=16+49
Ba=65
X=7.
9x-7y=63
9x-7 x 0=63
9x - 0=63
9x=63
X=7.
Y=-9
9 x 0 -7y=63
