find the mRF if m angle FNR= 38 degrees

so you can use that to find the actual distance x that 3 inches represents on a map

okay for the first one I got B as my answer and the second question I got C

why B for the first one?

you know the distance on the paper map, it's 7 inches
it's not z inches

oh haha I ment A sorry!

|dw:1364427190413:dw|

i meant to write z miles, not z inches

but hopefully you get the idea

the scale is this
|dw:1364427313903:dw|

oh first on is C huh?

put the two side by side to get
|dw:1364427383477:dw|

yep so its C!:)

yep, C it is

1 inch/10 miles = 7 inches/z miles
or just
1/10 = 7/z

alright how about second one?

we want arc RF, so we need to find central angle FDR

to find the central angle, you use the inscribed angle theorem

this central angle here
|dw:1364427601352:dw|

is equal to 2 times any inscribed angle which cuts off the same arc

alright so my answer would be D

yep 76

thanks!
