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.
Answer: Tracey attended 70% of the basketball games.
Step-by-step explanation:
<h3>you would multiply 14 by 100</h3><h3>then you would multiply 20 by x</h3><h3>that equals 1400=20x</h3><h3>then you divide both sides of the equal sign by 20</h3><h3>and get 70%</h3>
Answer:
x=120, y=70
Step-by-step explanation:
X must be 120 degrees as it is on a parallel line.
The outer+interior angles of a triangle on a straight line must be supplementary, so the second angle of the triangle is 180-120=60.
All interior angles of a triangle add up to 180 degrees: 50+60+y=180
y+110=180
y=70
