Answer:
A
Step-by-step explanation:
The 3 angles need to equal 180
The middle angle is given as 100.
180 -100 = 80
There is an x on each side so you have 2x
2x = 80
X = 80/2
X = 40 degrees
I think it 0.64 because if you think about it 6 marble in the pouch won’t be enough for 2.5 gram of vintage glass so instead try to put in and see how much it fit. 3.14 - 2.6 = 0.64
