Question

Find the missing side of the triangle

Answer 1

x = 8km

Explanation:

Use Pythagorean Theorem:

c2 = a2 + b2

In the diagram given, the hypotenuse (c) is 17 so substitute these values into the equation

17^2 = x^2 + 15^2

Take 15 to the power 2, to the other side.

17^2 - 15^2 = x^2

Solve to get

64 = x2

Square root both sides so

x = 8

Answer 2

x= 8 km

Explanation:

measurement used:

When getting measurement the missing side occupies 1 more than a half of 15km
