B) 60.26 degrees
Step-by-step explanation:
The above picture might help you to visualise the problem better. Moreover, do also note that the angle of depression is calculated from the horizontal. Let a be the angle of depression.
tan a = <em>o</em><em>p</em><em>p</em><em>o</em><em>s</em><em>i</em><em>t</em><em>e</em><em> </em>/ <em>a</em><em>d</em><em>j</em><em>a</em><em>c</em><em>e</em><em>n</em><em>t</em>
tan a = 21 / 12
a = tan inverse (21/12)
<u>a</u><u> </u><u>=</u><u> </u><u>6</u><u>0</u><u>.</u><u>2</u><u>6</u><u> </u><u>d</u><u>e</u><u>g</u><u>r</u><u>e</u><u>e</u><u>s</u>
Hence angle of depression is <u>B</u><u>)</u><u> </u><u>6</u><u>0</u><u>.</u><u>2</u><u>6</u><u> </u><u>d</u><u>e</u><u>g</u><u>r</u><u>e</u><u>e</u><u>s</u>

b) 10 cubic yard is less than 11 2/3 cubic yard. So, it will fit in the wood shed.
7) Right side rectangular prism:
l = 16 in
w = 5 in
h = 20 - 14 = 6 in
Volume 1 = 16 * 5 * 6 = 480 cubic inches
Left side rectangular prism:
l = 9 in
w = 5 in
h =14 in
Volume 2 = 9 * 5 * 14 = 630 cubic in
Volume of composite solid = 480 + 630 = 1110 cubic inches
