+153 A. Given that TAN(A)==1.7124, find angle A
B. Given that SIN(A)=0.7734, find angle A
+2440 You have not specified whether to use degrees or radians. Here are a few rules you should know, though
If \(\tan(a)=x\Rightarrow\tan^{-1}(x)=a\)
If \(\sin(a)=x\Rightarrow\sin^{-1}(x)=a\)
This rule is try for cosine as well.
Therefore, we can solve for a by using the inverse tangent function on the calculators.
\(\tan(a)=1.7124\Rightarrow\tan^{-1}(1.7124)=a\)
Degree Mode: \(59.716109581458\)
Radian Mode: \(1.042242728678\)
\(\sin(a)=0.7734\Rightarrow\sin^{-1}(0.7734)=a\)
Degree mode: \(0.013497966524\)
Radian mode: \(0.698572106543\)
