Answer:
∠ ABC = 81° , ∠ FEC = 90°
Step-by-step explanation:
Since AB ≅ BC then Δ ABC is isosceles.
The median BE is therefore
The angle bisector of ∠ ABC and
BE bisects AC at right angles.
Thus
∠ ABE = ∠ CBE = 40° 30' , then
∠ ABC = 2 × 40° 30' = 81°
Since BE is perpendicular to AC then
∠ FEC = 90°
if Joyce saved $70
at 75% off, Joyce saved 25%
so, $70 is 25%
To find the total price which is 100%, multiply $70 by 4 ( because 25% x 4 = 100% )
so the original price is $70 x 4 = $280
100-2=98
2250/100x98=2450
100-3 = 97
2450/100 X 97= 2376.50
