Answer:
Step-by-step explanation:
This is a right triangle trig problem. The base of the right triangle is the distance that Donna if from the flagpole; the flagpole is the side opposite the reference angle which was given as 26, and we are looking for the height of the flagpole, h. The trig ratio that uses the side opposite over the side adjacent is the tangent ratio, specifically:
and
123tan(26) = h so
h = 60.0 rounded to the nearest tenth. But that is only the height from her line of vision and up, not the whole height. In order to find the whole height, we have to add in her height up to her line of vision which is 5.3 feet. Therefore, the height of the flagpole is
60.0 + 5.3 = 65.3 feet.

Step-by-step explanation:
This cube would have a surface area of 726 inches squared. To get this you take the cube root of 1331 to get 11. This 11 is a side length so you use it to find the area of a side: 11*11 = 121. Then multiply this 121 by 6 because there are 6 sides to a cube and get 726.
