Answer:
60 I think
Step-by-step explanation:
draw a straight line to make it a triangle then you know that angles in a triangle add up to 180.
so,
180-140=40
180-100=80
40+80=120
180-120=60
x=60
I think it's 60
Answer:
D it is d my guy you have fun with that
100*2.2=220
80*2=176
220+176=396
So the two trains will take 2.2 hours so that they are 396 miles apart.
That would be 2.1 because if it's in decimal it's 2.1
Answer:
x=4.5
Step-by-step explanation:
The sum of all the angles in a square=360°
20(4.5)=90
90×4=360
