PLZ HELP!Professor Carlson calculates a 63% average on a chapter test from her first-year physics class. Fearing the test was too difficult, professor Carlson enters the scores into a computer program which generates the following box-and-whisker plot. Which of the following statements is an appropriate conclusion for professor Carlson to draw from the plot? A.
Every student in the class scored between a 72% and 92%. The test was not too difficult.
B.
Only about one-third of the class received a 72% or better. The test was obviously too difficult.
C.
At least half of the class earned received a 72% or less on the test. The test was probably too tough.
D.
Three-quarters of the class was able to earn a 72% or better on the test. Overall, students were able to perform. Thus, the test was appropriate.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
