Answer:

The width of the rectangle is \sqrt{35} and the length of the rectangle is 2\sqrt{35}

Step-by-step explanation:

l = 2w

A = l * w

A = 2w * w

70 = 2w^{2}

35 = w^{2}

\sqrt{35} = w

2\sqrt{35} = l

Identify the exact value of 157.5°
steposvetlana [31]
<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>
