Answer:
C
Step-by-step explanation:
note that sin x = cos(90 - x ) ← Cofunction identity
If x = 36 then 90 - x = 90 - 36 = 54
Hence sin 36° = cos 54° → C
11x3 or 16.5 to the power of two or: 30+3.
c=57.8
6*7+4=46
5*7=35
c= 46^2+35^2=57.80138
the answer is $99.49
30 percent of $74.99 is $24.50
74.99 + 24.50 = $99.49
