Question 807838: Here is the question.
Expert trails at ski resorts are designated as double black diamond trails. If the top and bottom of the diamond on a sign are 30 angles and the diamond is 30 cm tall from top to bottom, what is the area of the diamond to the nearest tenth of a square centimetre?
Here is my answer, I'm not sure if it full understand the question that's why I'm asking.
tan15=x/15
x=tan15(15)
x=4.02
4.02+4.02=8.04
Area=(b(h))/2
Area=(8.04(15))/2
Two triangles in a diamond
Area=60.3(2)
The area of the diamond is 120.6 sq. cm.
Is that right?
You can put this solution on YOUR website! There are two diamonds on a "double black diamond trail sign", but
the problem only asks for the area of one of them so
you are correct :-)
