find the angle measure to the nearest degree.
cos a = 0.4226
a=

Explanation:

Step1: Use inverse - cosine function

$A=\cos^{-1}(0.4226)$

Step2: Calculate the value

Using a calculator, $A\approx65.00^{\circ}$

Step3: Round to nearest degree

Rounding $65.00^{\circ}$ gives $65^{\circ}$

Answer:

$65^{\circ}$
