Question

If , then what is mto the nearest degree?

Answer 1

Given:

`\cos \angle A=(342)/(1000)`

To find:

The measure of angle A to the nearest degree.

Solution:

We have,

`\cos \angle A=(342)/(1000)`

It can be written as

`\angle A=\cos ^(-1)(342)/(1000)`

`\angle A=70.00123^\circ`

`\angle A=70^\circ`

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