Question

Find the missing side of the triangle. Round your answer to the nearest tenth if necessary.

Answer 1

X = 5 km

Explanation:

(Since the triangle is a right triangle, we can use the Pythagoras Theorem)

Using the Pythagoras Theorem,
x^2 = 13^2 - 12^2
x^2 = 169 - 144
x^2 = 25
x = 5 km

Answer 2

Answer

Missing side of triangle is 5 km.

step -by -step explanation

Here we have

Perpendicular = 12 km

missing side = base = x

hypotenuse = 13 km

And since , we have given right triangle in a question . So we can use Pythagoras theorem

Pythagoras theorem

(Perpendicular) ²+(Base) ²= (hypotenuse) ²

substitute the value

( 12 km ) ² + ( x ) ² = ( 13 km ) ²

Multiplying the values

144 km ² + x² = 169 km²

now Solve it

x ² = 169 km² - 144 km²

x ² = 25 km ²

x = √25 km²

x = 5 km.

Hence , missing Side of triangle is 5 km.
