Answer:
Step-by-step explanation:
(1). m∠5 = 40° → (a) Given
m∠2 = 140° → (b) Given
∠5 and ∠2 are supplementary angles → (c) Interior angles on the same side of the transversal.
∠5 and ∠2 are the same side interior angles → (d) Both angles are supplementary
a║b → (e) By interior angles theorem of the parallel lines.
(2). Statements Reasons
1. l║n 1. Given
2. ∠2 ≅ ∠6 2. Corresponding angles
3. ∠4 ≅ ∠2 3. Vertical angles
4. ∠6 ≅ ∠4 4. Transitive property of equality
(3). Statements Reasons
1. ∠1 ≅ ∠5 1. Given
2. ∠4 ≅ ∠1 2. Vertical angles
3. ∠4 ≅ ∠5 3. Alternate interior angles
4. p║r 4. Definition of parallel lines
Assuming yo mean $8.798
ok, so look at the cents ones
9
look at previous term
8
8 is bigger than 5 so round up
9 rounded up is 10
so
8.80 is rounded
Answer: b
Step-by-step explanation:
because it's all on the line.
The student simplified wrong because when he brought a to the numerator, he forgot to change the sign of the exponent. Instead of getting a^2 in the numerator (by adding 4 + -2), he should have gotten a^6 (by adding 4 + 2)
