tan = opp/adj
x = 13(tan 45)
x = 13
//
a² + b² = c²
13² + 13² = 338²
square root of 338 is not a rational number so turn into mixed radical.

Answer:
-2
Step-by-step explanation:
For the given expression to be undefined, this means that the denominator must be zero.
From the given expression, the denominator is x + 2
Equating this to zero;
x+2 = 0
Subtract 2 from both sides
x+2-2 = 0 -2
x = -2
Hence the value of x that makes it undefined is -2
