they form a figure with a long side of 12f and a short side of 9f what is the diagonal of the figure be to make sure the base of
Minchanka [31]

The diagonal of a rectangular figure is an illustration of Pythagoras theorem

The diagonal of the figure is 15f

The given parameters are:

\mathbf{Long= 12f}

\mathbf{Short= 9f}

The diagonal is calculated using, the following Pythagoras theorem

\mathbf{Diagonal = \sqrt{Long^2 + Short^2}}

So, we have:

\mathbf{Diagonal = \sqrt{(12f)^2 + (9f)^2}}

Evaluate all squares

\mathbf{Diagonal = \sqrt{144f^2 + 81f^2}}

Evaluate like terms

\mathbf{Diagonal = \sqrt{225f^2}}

Take square roots

\mathbf{Diagonal = 15f}

Hence, the diagonal of the figure is 15f

So if angle 4 is given to find angle 3 all we have to do is subtract the angle that is given from 180

180-138=42

Therefore angle 3 = 42
