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:
$6.48
Step-by-step explanation:
Initially calculate the 10% discount on $1.60, which results in $1.44. Then multiply $1.44 by 4.5 to find the total, yielding $6.48.
