The measure of angle ∠A will be 70 degrees.

What is trigonometry?

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

If cos∠A = 342 / 1000

Then the measure of angle ∠A will be

cos∠A = 342 / 1000

Then we have

∠A = cos⁻¹ (342 / 1000)

∠A = cos⁻¹ 0.342

∠A = 70⁰
