Answer:

Step-by-step explanation:

Call high street is a, using  Pythagorean Theorem we have:

x^2 = 4 + a^2

b^2 = a^2 + 36

64 = x^2 + b^2

so we have x^2 = 16, a^2 = 12, b^2 = 48

so x= 4

Answer:

x = 28

Step-by-step explanation:

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

Then x/(x +10) = 42/(42 +15)

x(57) = 42(x + 10)

57x = 42x + 420

15x = 420

x = 28
