Answer: It was marked down by 35%
Step-by-step explanation:
1. find the difference of the two prices, 68-44.20=23.8
Take the fraction 23.8/68 (because that is how much the price changed and you need to find what percent that is.
You get 35%
 
        
             
        
        
        
3/4x-12-5=15
3/4x-17=15
3x-68=60
3x=60+68
3x=128
X=128/3
        
             
        
        
        
Answer:
Area of trapezium = 4.4132 R²
Step-by-step explanation:
Given, MNPK is a trapezoid
MN = PK and ∠NMK = 65°
OT = R.
⇒ ∠PKM = 65° and also ∠MNP = ∠KPN = x (say).
Now, sum of interior angles in a quadrilateral of 4 sides = 360°.
⇒ x + x + 65° + 65° = 360°
⇒ x = 115°.
Here, NS is a tangent to the circle and ∠NSO = 90°
consider triangle NOS;
line joining O and N bisects the angle ∠MNP 
⇒ ∠ONS =  = 57.5°
 = 57.5°
Now, tan(57.5°) = 
⇒ 1.5697 = 
⇒ SN = 0.637 R
⇒ NP = 2×SN = 2× 0.637 R = 1.274 R
Now, draw a line parallel to ST from N to line MK
let the intersection point be Q.
⇒ NQ = 2R
Consider triangle NQM,
tan(∠NMQ) = 
⇒ tan65° =  
 
⇒ QM =  
 
QM = 0.9326 R .
⇒ MT = MQ + QT
           = 0.9326 R + 0.637 R  (as QT = SN)
⇒ MT = 1.5696 R
⇒ MK = 2×MT = 2×1.5696 R = 3.1392 R
Now, area of trapezium is (sum of parallel sides/ 2)×(distance between them).
⇒ A = ( ) × (ST)
) × (ST)
        = ( ) × 2 R
) × 2 R
        = 4.4132 R²
⇒ Area of trapezium = 4.4132 R²
