Your answers are
A = 35.7°
B = 67.6°
C = 76.7°

cosine law

a^2 = b^2 + c^2 -2bc \cos A \\
-2bc \cos A = a^2 - b^2 - c^2 \\ \\
\cos A = \dfrac{a^2 - b^2 - c^2}{-2bc} \\ \\
A = \cos^{-1}\left[ \dfrac{a^2 - b^2 - c^2}{-2bc} \right] \\ \\
A = \cos^{-1}\left[ \dfrac{12^2 - 19^2 - 20^2}{-2(19)(20)} \right]  \\ \\
A = 35.723697

A = 35.723697
sine law for the rest of the angles

\displaystyle
\frac{\sin B}{b} = \frac{\sin A}{a} \\ \\
\sin B = \frac{b \sin A}{a} \\ \\
B = \sin^{-1} \left[ \frac{b \sin A}{a}  \right] \\ \\
B = \sin^{-1} \left[ \frac{19 \sin 35.723697 }{12}  \right]  \\ \\
B \approx 67.58886795

B = 67.58886795
All angles in triangle sum to 180 so find C with that

A + B + C = 180
C = 180 - A - B
C = 180 - 35.723697 - 67.58886795
C = 76.7°

In order for a ladder to reach a height of 10 feet, it needs to be placed at a 75° angle to the ground. The ground already has a
Dmitry [639]

Since the ground already has an elevation of 15 degrees, the ladder needs to

be set at 60 degrees to reach a height of 10 ft.

In order for a ladder to reach a height of 10 feet, the ladder needs to be

placed at 75 degrees angle to the ground. This is when the ground has no

angle of elevation or when it flat.

Now, if the ground has an angle of elevation of 15 degrees , the degrees in

angle the ladder needs to be set can be solved as follows:

<h3>Angles in degree: </h3>
  • 75  - 15 = 60 degrees

Therefore, the ladder needs to set at an angle of 60 degrees if the

elevation of the ground is already 15 degree. The elevation of the ground

will complement the angle in degrees required for the ladder to reach 10

feet.
