Answer:
5
Step-by-step explanation:
5 > 0 (True)
Plug in 5 for t in the equation.
t² - 25 = 0
(5)² - 25 = 0
(5 * 5) - 25 = 0
(25) - 25 = 0
0 = 0 (true).

(1 × 10) + (2 × 10) + (3 × 10) =
10 + 20 + 30 = 60 different ways.
Using the law of Cosines:
c^2 = 10^2 + 8^2 - 2*10*8*cos(105)
c^2 = 205.41
c = SQRT(205.41)
c = 14.3
The answer is D
