Question

A= what???? In kilometers

Answer 1

Answer:

a = 116 km

Step-by-step explanation:

180 - (34 + 30) = a

180 - 64

= 116 km

Answer 2

To find a, we can use Pythagoras theorem, where:

a^2+b^2 = c^2

a and b is the width and length, while c is the longest side.

In this case:

30^2+a^2 = 34^2

Put the numbers without unknown on one side:

a^2 = 34^2 - 30^2

a^2 = 256

a = _/256

a = 16

Therefore, a = 16km.

Hope it helps!
