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
