Diego is planning to make a wooden cookbook stand for his mom. The depth of the stand will be 10 inches and will hold a cookbook at a 40° angle, as shown in the following design.
40
10 in
Diego wants to know if the length of the slanted side will be large enough to hold a cookbook. Which equation can be used to find x, the length
of the slanted side?
OA. sin(40%) = 10 in
B. cos(40%) = 10 in
Octan(40°) = no in
D. Cos(40%) =
10.in
