Step-by-step explanation:
Answer:
∠1 ≅ ∠2
Step-by-step explanation:
As shown in the figure:
We need to prove e ∥ f using the congruent angle.
So, check the options:
A) ∠2 ≅ ∠4 ⇒ (Wrong)
B) ∠1 ≅ ∠2 ⇒ (True) because a ∥ b (Given)
C) ∠2 ≅ ∠3 ⇒ It is required to prove that to prove e ∥ f , it can't be used.
D) ∠1 ≅ ∠4 ⇒ (Wrong)
The complete sentence will be:
We see that ∠1 ≅ ∠2 by the alternate exterior angles theorem.
Therefore, angle 2 is congruent to angle 3 by the transitive property.

<u>Answer:</u>
Helen's salary increased more.
<u>Step-by-step explanation:</u>
We know that Clint's salary increased from $24000 to $36000 over a three-year period.
So the increase in Clint's salary will be = 36000 - 24000 = $12000
While Helen's salary increased from $29000 to $43, 500 over the same period of 3 years.
So the increase in Helen's salary will be = 43500 - 29000 = $14500
Therefore, in absolute terms, Helen's salary has increased more.
