Answer:
Step-by-step explanation:
Multiply both the denominator and numerator by square root of 3 to rationalize the denominator.
2(w+60) + 2w= 520
perimeter of a rectangle = 2(length)+2(width)
length=w+60ft
width=w
perimeter=520ft
520ft=2(w+60)+2w
R.A.C.E Formatted Paragraph:
The temperature in Grand Junction was 73° warmer then Breckenridge that morning. I know this because I started off thinking about how I could get from -28 to 45. I then decided to subtract -28 from 45. This left me with 73°, which is the <em>change</em> in temperature.
hope this helps <3
Use the formula.
Area = (1/2)*13*10*sin(72°) ≈ 61.8 units².
