V = 65.9 cubic millimeters
Answer:
x = 4
y = 6
z = 8
Step-by-step explanation:
keep in mind I'm not doing that well with geometry so this might all be wrong lol
x is part of a 30 60 90 triangle.
so x is 4
next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.
4 + 6 = 10
10^2 = 100
100 = a^2 + b^2
y = 6 and z = 8 bc 36 + 64 = 100
