Question 526171
North avenue is 48 feet wide when it ends at main street.
 a 73 foot long diagonal crosswalk allows pedestrians to cross main street to or from either corner of north avenue. determine the width of main street.
:
Let m = the width of main street
:
A right triangle is formed with the cross walk and the width of the two streets
where
Leg 1 = m
Leg 2 = 48
Hypotenuse = 73
:
m^2 + 48^2 = 73^2
m^2 + 2304 = 5329
m^2 = 5329 - 2304
m^2 = 3025
m = {{{sqrt(3025)}}}
m = 55 ft is the width Main street
