Answer 1

hope this would help you

Answer 2

a) The distance from Spruce Road to Pine Road along Oak Street is 11 miles,

b) The distance from Spruce Road to Pine Road along Main Street is 22 miles.

Explanation:

a) Let x be the distance from Spruce Road to Pine Road along Oak Street,

By the given diagram,

`tan 60^(\circ)=(11√(3))/(x)` ( Since, tan Ф = Perpendicular / Base )

`√(3)=(11√(3))/(x)`

`x=(11√(3))/(√(3))=11`

Hence, the distance from Spruce Road to Pine Road along Oak Street is 11 miles

a) Let y be the distance from Spruce Road to Pine Road along Main Street,

Again, by the given diagram,

`y^2=(11√(3))^2+(11)^2` ( By the Pythagoras theorem )

`y^2=363+121=484\implies y = 22`

Hence, the distance from Spruce Road to Pine Road along Main Street is 22 miles.
