Answer: ∠B = 42° ∠A = 23° ∠F = 115°
Step-by-step explanation:
∠B≅∠C alternate interior angles 42°
∠CDF is supplementary to ∠CDE,
so m∠CDF = 23° and ∠FAB≅∠CDF so m∠FAB= 23°
<em>also ∠A ≅ CDE corresponding angles 157° ∠FAB is suplementary to ∠A </em>
<em>so 180 - 157 = 23 gives the m∠FAB</em>
The sum of the angles of a triangle is 180°, so m∠AFB = 180 -(23 +42)
180- 65 = 115 = m∠F
There is no restriction upon x for that function therefore the domain is all real numbers. x=(-oo, +oo)
Answer:
X=5
Step-by-step explanation:
There are many irrational numbers between 4 an 9, so Mr. DeMouy is right. Two possible examples can be, 4.01001000100001...... another example would be 8.010100100010000100000....... These numbers are irrational because they're non-terminating so it goes on forever.
