Answer: First option.

Step-by-step explanation:

Given the following equation provided in the exercise:

\sqrt[3]{x+8}=-4

You can follow the steps indicated below in order to find the solution of this equation:

1. Cubing both sides of the equation, you get:

(\sqrt[3]{x+8})^3=(-4)^3\\\\x+8=-64

2. Finally you must subtract 8 from both sides of the equation:

x+8-8=-64-8\\\\x=-72

You can notice that this solution matches with the first option.

Setler [38]
The answer would be D i think because if the two angles are to equal 72, and one of the angles equals 42, 72-42= 30. to find x, you’d do 30/6 which equals 5. so x=5 and the angle measure would be 30
