In the middle of town, State and Elm streets meet at an angle of 40º. A triangular pocket park between the streets stretches 100 yards along State Street and 53.2 yards along Elm Street. What formula for the area of the pocket park would you use

A = 1/2(sin40º)(53.2 yd) A = 1/2 (sin100º)(53.2 yd) A = (100 yd)(sin50º)(53.2 yd) A = 1/2 (100 yd)(sin40º)(53.2 yd)

draw it up, looks like you are given side - angle - side values

The area of a triangle is (1/2)*base*height

maybe easier to orient it different.... |dw:1441237983462:dw|

So the last one then
DanJS
  • DanJS
so the area of the red triangle is (1/2) * base * height = (1/2) * 100 * h
DanJS
  • DanJS
since h is part of a right triangle, you can use trig function to rewrite its value

you get what i did so far?, almost done

Yeah kinda lol
DanJS

Since you already know the hypotenuse, you can use sin(40) to find h, sin(40) = opposite side / hypotenuse sin(40) = h / 53.2
DanJS
  • DanJS
so h = 53.2 * sin(40)

Omg so I was right. It's 1/2(100)(Sin40)(53.2)
DanJS
  • DanJS
yeah, you guess or do that work? :)

Did the work just wasn't sure. Mind helping me with one more? Then I'm done
