Question

Find the missing side measure

Answer 1

Answer:

B) 178 mi

Step-by-step explanation:

$a^{2} +b^{2} =c^{2}$

$78^{2} + 160^{2}=c^{2}$

6084+25600=$c^{2}$

31684=$c^{2}$

$\sqrt{31684} =\sqrt{c^{2}}$

178=c

Answer 2

ANSWER:

Using pythagorean theorem,

x² = (78)² + (160)²

x² = 31,684

x = √31,684

x = 178mi.

So, Correct choice - [B] 178mi.
