Which inequality represents all values of x for which the quotient below is<br> defined?
garri49 [273]

Answer:

Option B: x > 0

Step-by-step explanation:

Option A is wrong because \sqrt{3(0)}will be 0. So, the inequality can't be divided by 0.

Option C is wrong because 1 will suffice this inequality. \sqrt{7}/\sqrt{3}=1.5 (approx)

Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).

Leaving us with only option B, which is the right answer.

geniusboy [140]

Answer:

Let the two supplementary angles be

we know sum of two supplementary angles is 180

2x + 3x = 180

5x = 180

x = 180/5

x = 36

2*36 = 72

3*36 = 108

Therefore the two supplementary angles are 72 and 108
