Question

pleasd answer the question given in the picture... the person who answers step by step and in detail will be marked as brainlist...​

Answer 1

therefore required distance = √ (12)² + (9)²

= √144 + 81

= √225

= 15 km

hence 15km is the answer.

hope it helps you.

Answer 2

Answer:

Its about base perpendicular and hypotenuse

Step-by-step explanation:

First here base=12km

perpendicular=4km

hypotenuse=?

Now by using the trigonometric formulA:;

h^2 =p^2 +b^2

where h= hypotenuse

p= perpendicular

b= base

continuing with the formula,

h^2 =(4km)^2 +(12km)^2

= 16km^2 +144km^2

= 160km^2

Rooting both sides , we get;

h= 12.64km
