90 = 35 + 22 + X
X represents the left over song choices (Jazz)
Answer:
Roughly, sinC = 15/17
=> AB = 15, BC = 17 => AC = sqrt(17^2-15^2) = 8
=> cos C = AC/BC = 8/17
Answer:
The answer to your question is L = 22; w = 15
Step-by-step explanation:
Data
length = L
width = w
Perimeter = 74
Condition
w = L/2 + 4
Formula
P = 2L + 2w
Substitution
74 = 2L + 2(L/2 + 4)
Simplification
74 = 2L + L + 8
74 = 3L + 8
74 - 8 = 3L
3L = 66
L = 66/3
L = 22
w = 22/2 + 4
w = 11 + 4
w = 15
