If 2xº and (2x - 20) are a pair of adjacent supplementary angles, find the<br>value of x.

kifflom [539]

Answer:

x = 50

Step-by-step explanation:

Since the two angles are supplementary, add them together and set them equal to 180 degrees

2x + 2x - 20 = 180 Combine like terms

4x - 20 = 180

+ 20 + 20 Add 20 to both sides

4x = 200 Divide both sides by 4

x = 50

Find the domain of f(x) = Square 3 x + 8

vagabundo [1.1K]

The question is a bit ambiguous: you may mean

$\sqrt{3x+8}$

$\sqrt{3x}+8$

Anyway, in both cases, the domain of a function involving a square root is found by imposing the content of the root to be greateer than or equal to zero. So, in the first case you have

$3x+8\geq 0 \iff 3x\geq -8 \iff x\geq -\dfrac{8}{3}$

In the second case, you have

$3x\geq 0 \iff x\geq 0$
