Answer:
w = 9.82
x = 66.73
Step-by-step explanation:
By applying tangent rule in triangle ABD,
tan(81°) = 
6.31 = 
w = 
w = 9.82
Similarly,
tan(39°) =
0.81 = 
0.81 = 
9.82 + x = 
x = 76.56 - 9.82
x = 66.74
Answer:
Each sweater costs $8.30
Step-by-step explanation:
j = jeans
s = sweater
3j + 3s = 105.69
3(26.93) + 3s = 105.69
80.79 + 3s = 105.69
-80.79 -80.79
3s = 24.9
/3 /3
s = 8.3 ($8.30)
Check:
3j + 3s = 105.69
3(26.93) + 3(8.3) = 105.69
80.79 + 24.9 = 105.69
105.69 = 105.69
Hope this helps!
The answer would be n=37 because…
40+n=77
subtract 40 on both sides, cancelling it out on the left side and 77-40=37 so:
n=37
