58.3 °

Step by step explanation:

Missing Information:

In this question the diagram is missing The following is the diagram of the given question to bind.

As we have seen the right tip is making the right angle i, e 90 ° is also the acute angle of the Hipotenuse: 20 cm and the vertical 10.5 cm

Now we have the best approximation of the angle ABC used the triangular function cosx.

Put a vertical value and hypotenuse in the previous formula we get
