ABCDEFGHIJKL 8426

The given is a regular hexagonal prism ABCDEFGHIJKL, which has all edges of the same length. Find the degree of the angle formed by the lines BK and CL in degrees.

Correct answer:

X =  53.1301 °

Step-by-step explanation:

a=1 BK=(2a)2+a2=(2 1)2+12=52.2361 CL=BK=2.2361=52.2361  sinX/2=BK/2a/2  x=2 arcsin(BKa)=2 arcsin(2.23611)0.9273 rad  X=x  °=x π180   °=0.9273 π180   °=53.13  °=53.1301=53°748"
