This guy is absolutly right. Priya, understand that answer. ☺?

Gaurav Seth 5 years, 9 months ago

Given that ABCD is a Rhombus and DE is the altitude on AB then AE = EB.

In a ΔAED and ΔBED,

DE = DE ( common line)

∠AED = ∠BED ( right angle)

AE = EB ( DE is an altitude)

∴ ΔAED ≅ ΔBED ( SAS property)

∴ AD = BD ( by C.P.C.T)

But AD = AB ( sides of rhombus are equal)

⇒ AD = AB = BD

∴ ABD is an equilateral traingle.

∴ ∠A = 60°

⇒ ∠A = ∠C = 60° (opposite angles of rhombus are equal)

But Sum of adjacent angles of a rhombus is supplimentary.

∠ABC + ∠BCD = 180°

⇒ ∠ABC + 60°= 180°

⇒ ∠ABC = 180° - 60° = 120°.

∴ ∠ABC = ∠ADC = 120°. (opposite angles of rhombus are equal)

∴ Angles of rhombus are ∠A = 60° and ∠C = 60° , ∠B = ∠D = 120°.

ANSWER

A manufacturer produces two models of bikes :model X and model Y.modelX takes 6 man-hours to make per unit, while model Y takes 10 man-hours per unit. There is total of 450 man-hours available per week. Handling and marketing costs are Rs.2000 and Rs.1000 per unit for modelsX andY respectively. The total funds available for these purposes are Rs.80000 per week. Profits per unit for models X andY are Rs.1000 and Rs.500, respectively. How many bikes of each model should the manufacturer producer so as to yield a maximum profit? Find the maximum profit.

We can assume f(x) to be y in this case so then the new equation will become:- y = x i.e. with slope=+1 and passing through origin. The the function will be strictly increasing for all real numbers satisfying the curve. I hope this clears your doubt.
