Answer:
the width is ≤ 38 feet
Step-by-step explanation:
the perimeter of a rectangle is given by the relation : 2*( length + width)
P ≤ 120
2 (L + W) ≤ 120
L + W ≤ 60 ,,, L = 22
22 + W ≤ 60
W ≤ 38 feet
<span>exact value of sin 157.5 without using a calculator
sin(157.5)=sin(315/2)
Identity: sin(x/2)=±√[(1-cosx)/2]
select positive identity since 175 is in the 2nd quadrant where sin>0
sin(315/2)=√[(1-cos315)/2]
cos 315=cos45 in quadrant IV=√2/2
sin(315/2)=√[(1-√2/2)/2]=√[(2-√2)/4]=√(2-√2)/2
sin(157.5)=√(2-√2)/2
check using calculator:
sin157.5º≈0.382...
√(2-√2)/2≈0.382...</span>
