Answer:

x ≥ -6

Step-by-step explanation:

Please use parentheses around the argument (input) of the sqrt function:

Better: sqrt( 1/3x + 2)

Much better: sqrt ( (1/3)x + 2)

The input to the sqrt function must be 0 or greater. Thus, we must solve the equation (1/3)x + 2 ≥ 0. Mult. all 3 terms by 3, we get x + 6 ≥ 0, or x ≥ -6.

emmasim [6.3K]

Answer:

$let \: \alpha \: be \: the \: 45 \\ \tan( \alpha ) = \frac{p}{b} \\ \tan(45) = \frac{x}{3 \sqrt{2} } \\ 1 = \frac{x}{3 \sqrt{2} } \\ x = 3 \sqrt{2} \\ by \: using \: pythagoras \: therom \\ {y}^{2} = {3 \sqrt{2} }^{2} + {3 \sqrt{2} }^{2} \\ {y}^{2} = 18 + 18 \\ y = \sqrt{36} \\ y = 6$
