Space diagonal angles

Calculate the angle between the body diagonal and the side edge c of the block with dimensions: a = 28cm, b = 45cm and c = 73cm. Then, find the angle between the body diagonal and the plane of the base ABCD.

Correct answer:

C =  35.9807 °
A =  54.0193 °

Step-by-step explanation:

A+C=90°  A=90C=9035.9807=54.0193°=54°110"
