Answer:
B
Step-by-step explanation:
In an isosceles triangle, the altitude is the median so the altitude splits the base into two segments with lengths of 5. We notice that x is part of a right triangle with legs of 5 and 12, therefore, using the 5 - 12 - 13 Pythagorean Triple, x = 13.
Tan^2 x + 5tan x + 3 = 0
Let tan x = m, then
m^2 + 5m + 3 = 0
m^2 + 5m + 25/4 = -3 + 25/4 = 13/4
(m + 5/2)^2 = 13/4
m + 5/2 = + or - sqrt(13) / 2
m = (√13 - 5)/2 or (-√13 - 5)/2
tan x = (√13 - 5)/2 or (-√13 - 5)/2
x = arctan((√13 - 5)/2) or arctan((-√13 - 5)/2)
x = 103.0837, 145.1149, 283.0837, 325.1149
