Question

Solve for t. If the answer is a decimal, round to the nearest tenth.

Answer 1

I believe the answer is 25 but I could be very wrong.
Explanation:
a^2(t)+b^2=c^2
a^2(t)+12^2=13^2
a^2(t)+144=169
-144 -144
a^2(t)= 25
25^2= 625
The square root of 625 = 25
t=25

Answer 2

Step-by-step explanation:

By Pythagoras' Theorem,

t² = 13² - 12²

=> t² = 169 - 144 = 25

=> t = 5 (as t is non-negative).
