If you use encoding Western ISO 8859-1 (you'll find this in the menu of your browser under view/encoding), then everyone can read your symbols.
As it is, I do not understand the part:
"They mark a point, A, 120 m along the edge of the water park from Briannafs house. The measure NBAÚ as and 75BANÚas."
Maybe all my questions have this problem. THanks for telling me how to fix it. The original question I posted was:
Noah and Brianna want to calculate the distance between their houses which are opposite sides of a water park. They mark a point, A, 120 m along the edge of the water park from Briannas house. The measure <NBA as 75 degrees and <BAN as 70 degrees. Determine the distance between their houses.
This requires essentially the solution of a triangle using the sine rule.
First, let us understand the problem by drawing a diagram:
∠NBA=75° = ∠B
∠BAN=70° = ∠A
(by sum of angles of a triangle =180°)
Distance BA = 120 m = n
Denote the distance NB = a
and the distance AN = b
Using sine rule, we have
n/sin(N) = a / sin(A)
and solving for a,
which is the distance between the houses (NOT the width of the river).
Thank you, that's what I got too:)
