A block bordering Sapphire Street is a right triangle. You start walking around the block, taking 125 paces on Sapphire Street and 102 paces on Diamond Street.
a. At what angle do Diamond and Sapphire Streets intersect?
b. How many paces must you take on Gold Street to complete the trip?
I cannot make sense out of your description.
Where doe Gold Street come from?
