Question

3 mm A cuboid is shown below. Calculate the size of angle to 1 d.p. 8 mm 14 mm 0​

Answer 1

The angle marked is solved to be 20.55 degrees

How to find the angle

To find the angle, we use trigonometry

Knowing that part of the cuboid is a rectangle,, we solve as follows

tan (angle) = 3/8

angle = arctan(3/8)

angle -= 20.55 degrees
