15. Transits and theodolites are tools that measure which of the following? (1 - Oheight and distance
Osoil quality and density
Orertical and horizontal angles
stress and pressure on beams

3. Vertical and horizontal angles

Explanation:

To find - Transits and theodolites are tools that measure which of the following?  

1. height and distance

2. soil quality and density

3. Vertical and horizontal angles

4. stress and pressure on beams

Proof -

There are two different kinds of theodolites: digital and non digital

Digital theodolites are used to display horizontal and vertical angles.

Transit is a surveying instrument that also takes accurate angular measurements.

Along with the transit, theodolites have mounted telescopes that can be rotated in different directions.

Both theodolites and transits can be used for similar projects, but there are slight differences between the two instruments.

So,

The correct option is - 3. Vertical and horizontal angles

the answer is hope this you.
