Two poles of equal height are standing opposite to each other on the other side of the road which is 80 m wide from the point in between them on the road the angle of elevation of the top of the polar 60 degree and 30 degree respectively find the height of pole and distance of the point from the pole

Answer»

<P>LET AB and CD be the two poles of EQUAL height and their heights be

H m. BC be the 80 m wide road. P be any point on the road. Let CP

be x m, therefore BP = (80 – x) .

Also, ∠APB = 60° and ∠DPC = 30°


In right angled triangle ABP,

Tan 60° = AB/AP

⇒ h/(80 – x) = √3

⇒ h = √3(80 – x)

⇒ x/√3 = √3(80 – x)

⇒ x = 3(80 – x)

⇒ x = 240 – 3x

⇒ x + 3x = 240

⇒ 4x = 240

⇒ x = 60


Height of the pole, h = x/√3 = 60/√3 = 20√3.

Thus, position of the point P is 60 m from C and height of each pole is 20√3 m.

4.

I will mark brainliestpls do these two questionsfull solution

Answer»

hello friend

here is you answer

plz mark as brainliest as you promised

1. let the CP be RS. 100 and MP be Rs. x

gain % after discount = 12%

gain = 12% of 100 = Rs. 12

⇒ SP of the article = CP + Gain

= Rs. (100 + 12) = Rs. 112

Discount % = 20%

Discount = 20% of Marked Price

 = Rs.20/100 * x

= Rs. 20x/100

= Rs. x/5

as da question says

marked Price - discount = SP

=> x - x/5 = 112

=> (5x - x)/5 = 112

=> 4x/5 = 112

=> x = 112 * 5/4 = Rs. 140

marked Price = Rs. 140

amount marked above the CP = MP - CP

= Rs. (140 - 100)

= Rs. 40

∴ % amount marked above the CP

= Amount increased/CP * 100

= 40/100 * 100

= 40%


2. Let, CP of the goods be Rs. x.

Marked Price = Rs.{x + (40% of x)} = Rs. x + 2x/5 = Rs. 7x/5

Discount % = 5%

Discount = 5% of Rs. 7x/5 = Rs.7x/100

SP of goods = Rs 1064

As per question-

Rs. 1064 = Rs. (7x/5 - 7x/100)

=>1064 = (140x - 7x) / 100

=>106400 = 133x

=> x = 106400 / 133 = Rs.800

PROFIT = SP - CP = Rs. (1064 - 800) = Rs. 264

Actual profit is Rs. 264.

I will mark brainliestgive full solution in step by steppls do these two questions

Answer»

here are your answers

pls mark as brainliest as you promised


1.Let the marked PRICE be X:


discount of 25%, THEREFORE purchase price is 75/100x = 0.75x

  

Profit = selling price -buying price (selling price = marked price)

          = x- 0.75x    

          =0.25x


gain % =  profit/ buying price(100)

         

            = 0.25/0.75(100)  =1/3(100)

      

            

            =33.3333%

2. let CP of GOODS be Rs.100

marked Price = 100 + (30% of 100) = Rs.130

discount % = 25%

discount = 25% of 130 = Rs.32.50

SP = Rs.(130- 32.5)

= Rs.97.50

⇒ CP> SP

Loss = (CP-SP)=Rs.(100 -97.50) = Rs.2.50

Loss % = Loss/CP * 100

= 2.50/100 * 100 

=2.5%
