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?
a sin(40) = 10 in
b. cos(40%) = 10 in
c. tan(40°) = 10 in
d. cos(40) = 10 in
