Answer:
should be 17
Step-by-step explanation:
Answer:
66°
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
x + y = z
5n − 19 + n + 7 = 144 − 6n
6n − 12 = 144 − 6n
12n = 156
n = 13
m∠z = (144−6n)°
m∠z = (144−6×13)°
m∠z = 66°
If L = length of each edge the
L^3 = 231
L = 6.136 in^3 to the nearest thousandth
The answer is .36363636363
