Answer the following in several complete sentences: What is the importance of using operational definitions in behavioral research? Be sure to define and give an example of an operational definition in your response

An operational definition is a statement of the procedures or ways in which a researcher is going to measure behaviors or qualities. For example, the operational definition of anxiety could be in terms of a test score, withdrawal from a situation, or activation of the sympathetic nervous system. Operational definitions are important because one must define the measured variables in order to properly measure it.

Hope I helped :)

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
