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

Area of triangle where A=50, b=31, c=18
Mrac [35]
Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]

This will NOT form a triangle.  The longest side (50) is greater than the sum of the other 2 sides.
