Question

Can anyone help me on any of these math problems? except for 7

Answer 1

The given information is:

We know the measure of two sides and one angle.

We can apply the Sine Rule to solve this problem. This rule states:

`\frac{\sin A}{\bar{BC}}=\frac{\sin C}{\bar{AB}}`

If we replace the known values, we can solve for angle A as follows:

`\begin{gathered} \sin A=(\sin C*BC)/(AB)=(\sin36\degree *24)/(31) \\ \\ \sin A=(0.59*24)/(31) \\ \\ \sin A=0.455 \\ \\ A=\sin^(-1)(0.455) \\ \\ A\approx27\degree \end{gathered}`

The measure of angle A is approximately 27 degrees.
