Question

Find side c if side a = 10 inches and side b = 4 inches.

Answer 1

Well... are you given that ABC is a right triangle, and that the c, or the missing side, is the hypotenuse?

Answer 2

^ I'm assuming yes, that's the case

Answer 3

use pythagorean theorem

Answer 4

\[10^{2}+4^2 = 116\]

Answer 5

\[\sqrt{116}=10.77\]

Answer 6

c= 10.77

Answer 7

\[\sqrt{10^2+4^2}=\sqrt{116}=2 \sqrt{29}≈10.77\]
that is if we assume that c is the hyp., .... but that is not necessarily the case.


\[\sqrt{10^2-4^2}=\sqrt{84}=2 \sqrt{21}≈9.17\]
can as well be though that 10 is the hyp., but i think that in your case, the hyp, is the MISSING side C.

Answer 8

a^2 + b^2 = c^2
10^2 + 4^2 = c^2
100 + 16 = c^2
116 = c^2
sq rt 116 = c
10.77 = c

Answer 9

thats only if c is the hypotenuse
