Question

If , then what is mto the nearest degree?

Answer 1

Given:

$\cos \angle A=\dfrac{342}{1000}$

To find:

The measure of angle A to the nearest degree.

Solution:

We have,

$\cos \angle A=\dfrac{342}{1000}$

It can be written as

$\angle A=\cos ^{-1}\dfrac{342}{1000}$

$\angle A=70.00123^\circ$

$\angle A=70^\circ$

Therefore, the measure of angle A to the nearest degree is 70 degrees.
