X times 1.28 = 448
X = 448 divide by 1.28
Answer:
x = 2.4
y = 31
Step-by-step explanation:
Angle B = 25x
BC = 31
therefore , this is an equilateral triangle all sides and angles are equal,
25x =60
x = 2.4
BC = BA = AC
y= 31
Answer:
A. 13 1/5
Step-by-step explanation:
=10 3/5 + 2 3/5
=53/5 + 13/5
=66/5
=13 1/5
I plugged it in to a truncated square pyramid calculator and got v=76
the formula for this shape is V=1/3(A squared+AB+B squared)H.
