Think about it, 64 band members split equally into 8 rows. Sounds like division, right? If we're going to split them into each row, that would be eight members for each of the eight rows.
So the answer is that 8 members was in each row.
Answer:
x=26
Step-by-step explanation:
4x-8+34+76-x=180
4x-x-8+34+76=180
3x+102=180
3x=180-102
3x=78
x=78/3
x=26
Using the cosine double angle formula,
(Note I took the positive case since 
terminates in the first quadrant)
Using the Pythagorean identity,
(Note I took the positive case since terminates in the first quadrant)
Answer:
x ≈ 14.5
Step-by-step explanation:
A = x²√(25+10√5)/4
A = 1.72a²
x² = A/1.72
= 363.27/1.72
≈ 211
x = √211
≈ 14.5
