Answer:
5
Step-by-step explanation:
True:
1) F(x) is read as "F of x".
3) F is the graph at a particular value of x.
5) y is equal to F(x).
1) F(x) is read as "F of x", then first is true.
2) F(x) is the vertical distance on the graph, then second is false.
3) F is the grap at a particular value of x, then third is true.
4) F(x) can be any real number, then fourth is false.
5) y is equal to F(x), then fifth is true.
Answer:
Yes, △ABC ∼ △FED by AA postulate.
Step-by-step explanation:
Given:
Two triangles ABC and FED.
m∠A = m∠B
m∠C = m∠A + 30°
m∠E = m∠F = 
m∠D =
°.
Now, let m∠A = m∠B = 
So, m∠C = m∠A + 30° = 
Now, sum of all interior angles of a triangle is 180°. Therefore,
m∠A + m∠B + m∠C = 180

Therefore, m∠A = 50°, m∠B = 50° and m∠C = m∠A + 30° = 50 + 30 = 80°.
Now, consider triangle FED,
m∠D+ m∠E + m∠F = 180

Therefore, m∠F = 50°
m∠E = 50° and
m∠D = 
So, both the triangles have congruent corresponding angle measures.
m∠A = m∠F = 50°
m∠B = m∠E = 50°
m∠C = m∠D = 80°
Therefore, the two triangles are similar by AA postulate.
