Pyramid

Pyramid has a base a = 5cm and height in v = 8 cm.

a) calculate angle between plane ABV and base plane
b) calculate angle between opposite side edges.

Correct result:

α =  72.65 °
β =  33.22 °

Solution:

tanα=va/2=85/2 α=arctan85/2=72.65=723846"
 tanβ/2=av2+(a/2)2 β=2arctanav2+(a/2)2 β=2arctan0.29827  β=33.22=33131"
