Answer 1

Given data:

The given figure is shown.

For figure A, the expression for sin(A) is,

`\begin{gathered} \sin A=(7)/(18) \\ A=\sin ^(-1)((7)/(18)) \\ =22.885^(\circ) \\ \approx23^(\circ) \end{gathered}`

Thus, the value of angle A is 23 degrees.

(b)

The vaue of tan(A) is,

`\begin{gathered} \tan (A)=(14)/(12) \\ A=\tan ^(-1)((7)/(6)) \\ =49.398^(\circ) \\ \approx49^(\circ) \end{gathered}`

Thus, the value of A is 49 degrees.

(c)

The value of cos(A) is,

`\begin{gathered} \cos (A)=(6)/(10) \\ A=\cos ^(-1)(0.6) \\ \approx53^(\circ) \end{gathered}`

Thus, the value of A is 53 degrees.

(d)

The value of tan(A) is,

`\begin{gathered} \tan A=(20)/(28) \\ \tan A=(5)/(7) \\ A=\tan ^(-1)((5)/(7)) \\ =35.53^(\circ) \\ \approx35^(\circ) \end{gathered}`

Thus, the measurement of angle A is 35 degrees.
