If , then what is mto the nearest degree?

Given:
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
To find:
The measure of angle A to the nearest degree.
Solution:
We have,
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
It can be written as
[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]
[tex]\angle A=70.00123^\circ[/tex]
[tex]\angle A=70^\circ[/tex]
Therefore, the measure of angle A to the nearest degree is 70 degrees.
