Question

Washington street and Vindale avenue intersect at a right angle. if the diagonal distance across the intersection is 15 meters and washington street is 9 meters wide, how wide is vindale avenue?

Answer 1

a^2+b^2=c^2
9^2+b^2=15^2
81+b=225
b= √144
b=12
I’m pretty sure it’s 12, hope this makes sense :)
