B:(3,-4)
2x-(-x-1)=10
X=3
Y=-3-1
Y=-4
I believe it's -2 but i'm not 100% sure.
The Multiplicative Identity Property. This means that you can multiply 1 to any number... and it keeps its identity! The number stays the same!
Answer:x=90° y=58° z=32°
Step-by-step explanation:
x=90
y=180-(90+32) sum of angles in a triangle is 180
y=58
y+90+z=180 they are supplementary
58+90+z=180
148+z=180
z=180-148
z=32
