Question

If the sides of a triangle are accurate to 3 significant digits, then angles should be measured to the nearest ____ of a degree or the nearest ____.

Answer 1

The angles of a triangle with sides measured to 3 significant digits should be measured to the nearest degree or minute.

Step-by-step explanation:

When the sides of a triangle are measured with 3 significant digits, the angles should be measured to the nearest degree or the nearest minute.

For example, if the sides of a triangle are measured as 12.345 cm, 15.678 cm, and 20.987 cm, then the angles should be measured to the nearest degree or minute.

Angles in a triangle can be calculated using trigonometric functions like sine, cosine, and tangent.
