Can someone explain the process of getting to Angle A? I know the answer is 44.1 but I need to show my work so can someone show
dsp73

Answer:

Step-by-step explanation:

First you have to calculate CB in order to use sin law to calculate ∠A

CB=\sqrt{18.4^{2} -13.2^{2} }

CB=12.8(correct to nearest tenth)

After that, use sin law to calculate ∠A,

\frac{18.4}{sin90} =\frac{12.8}{sinA}       or    \frac{sin90}{18.4} =\frac{sinA}{12.8}

sinA=0.695...

A=44.079...

  =44.1(corrext to the nearest tenth)

Is that clear enough for you?
