The value of the angle is 60. When I first saw the problem I noticed there were two supplementary angles which means they added to 180*. I wrote the equation (2x) + (x) = 180. To solve I divided by 3. What was the question he answered? Give the question and explain how you know. Include either the diagrams or a description of the diagrams. Include at least 4 sentences.

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
