Researchers in Canada performed an experiment with university students to examine the effects of multitasking on student learning. The 40 participants in the study were asked to attend a lecture and take notes with their laptops. Half of the participants were randomly assigned to complete other online tasks not related to the lecture during that time. These tasks were meant to imitate typical student Web browsing during classes. The remaining students simply took notes with their laptops.
At the end of the lecture, all participants took a comprehension test to measure how much they learned from it. The results: students who were assigned to multitask did significantly worse (11%) than students who were not assigned to multitask.
1. Describe how the researchers could have carried out the random assignment.

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal interior angles
so
The triangles of the figure are isosceles triangles, because they have two equal sides
Remember that
The sum of the interior angles in the triangle is equal to 180 degrees
In the triangle of the left we have that
The measure of the two equal interior angles are 5x and 5x and the measure of the third angle (vertex angle) is 2x by vertical angles)
so
solve for x
