4. The two triangle are congruent.
Type this question, It is blurry.
D. -10 cause it would be y=4x-10
Answer:
Dimension
Height =29.01
Breadth=38.70
Step-by-step explanation:
Printed area is =386 and margins as specified.
For printed area let height be x and breadth be y.
x*y=386 ⇒ y =
Now considering the margins
Height = x+6+6=x+12
Weidth = +8 +8= + 16
Area of poster to be minimised =(x+12)( + 16)
Differentiate above area with respect to x and equate to zero to find extrema.
= 16 -=0
x=17.01
Now plug value of x in height and breadth
Height =29.01
Breadth=38.70
