6-77.

​An $8$-foot ladder leaning against a house touches the wall $7$ feet above the ground. Draw a diagram and determine the measure of the angle created by the ladder and the ground.

Use an inverse trig function to calculate the angle measurement.

$\text{sin}^{-1} \left (\frac{7}{8} \right )\approx ?$
