Answer:
B
Step-by-step explanation:
To solve this you do 80/100=.8
You than do .8×60= 48
2x^2 + 2y^2 + 2xy I think
Step-by-step explanation:
x+100°=180°{being straight angle}
x=180-100
x=80°
again,
45°+x+y=180°{sum of angle of triangle}
45+80+y=180
y=180-125°
y=55°
hope it helps.
Answer:
A - the real answer is 7
Step-by-step explanation:
