The dating technique which was used to establish the age of the volcanic ash at the Laetoli site is: potassium-argon (K/A) dating.
<h3>What is absolute dating?</h3>
Absolute dating can be defined as a radioactive process that is typically used to accurately determine the age of a rock, volcanic ash or fossil, by measuring the decay of the isotopes that is associated with the rock or within the fossils.
Thus, scientists can accurately determine the age of a volcanic ash, rock or fossil by measuring its isotope concentration such as through the use of potassium-argon (K/A) dating.

Explanation:
Hi there!
Given;
one angle (let be x)= 141°
Then;
141° + angle 3 = 180°. {being linear pair}
angle 3 = 180°-141°
angle 3 = 39°
Therefore, angle 3 is 39°.
Now; angle 3 = angle 4 = 39° {alternate angles are equal}
Therefore, the measure of angle 4 is 39°.
