In your calculator, put cos-1 (0.4612) you will get 62.5 degree ~63 degrees. That's it.

cos B = 0.4612

B = cos ^(-1) 0.4612

B = 62.54 degrees

cos B = 0.4612

B = Arcos(0.4612)

B = 62.54 degrees

So for this you're given the value or output of the function cosb=o.4612 like f(x)=y now in order to solve for x or in this case b you need to use the inverse of the function; cos^{-1 }which in this case is also a function, it takes the output value and gives you your input!

So cos^{-1}0.4612=62.45^{o }

Given $\cos B=0.4612$cosB=0.4612

we can use the function arccos, or inverse cosine, to find the angle.

This appears as $\cos^{-1}$cos^{−1} on your calculator.

Arccos(0.4612) = 1.09 radians

1.09 radians * (180 degrees/Pi radians) = 62.5 degrees

we can use the function arccos, or inverse cosine, to find the angle.

This appears as $\cos^{-1}$cos

^{−1}on your calculator.Apply to both sides

$\cos^{-1}\cos B=\cos^{-1}0.4612$cos

^{−1}cosB=cos^{−1}0.4612$\cos^{-1}\cos B=B$cos

^{−1}cosB=B$\cos^{-1}0.4612=62.5º$cos

^{−1}0.4612=62.5ºTo the nearest degree we get 63º
