Response: ∠B = 42° ∠A = 23° ∠F = 115°
Detailed explanation:
∠B is congruent to ∠C alternate interior angles 42°
∠CDF is supplementary to ∠CDE,
thus m∠CDF = 23° and ∠FAB is congruent to ∠CDF therefore m∠FAB= 23°
also ∠A is congruent to ∠CDE corresponding angles 157° ∠FAB is supplementary to ∠A
which leads to 180 - 157 = 23 giving m∠FAB
The sum of angles in a triangle amounts to 180°, so m∠AFB = 180 -(23 +42)
This results in 180- 65 = 115 = m∠F
Answer:
The first equation is y = 1.5x - 6
The second equation is y = -4x + 6.1
The solution is (2.2, -2.7)
Step-by-step explanation:
Answer:
118.2°
Step-by-step explanation:
Dos líneas paralelas x e y son cortadas por la transversal w (ver el diagrama adjunto).
Se forman 8 ángulos (denominados 1, 2, 3, 4, 5, 6, 7 y 8).
Los ángulos 1 y 6 son ángulos del mismo lado cuando dos líneas paralelas x e y son cortadas por la transversal w.
Dos ángulos del mismo lado son suplementarios (suman 180°). Esto significa
Dado
