Triangle ABC is an equilateral triangle and AD is an angle bisector of angle A , AD=3cm1. find AC?2.find the perimeter of triangle ABC?​

Answer»

Answer:

Step-by-step explanation:

As the TRIANGLE ABC is an equilateral triangle

Hence ,

AB= BC = AC .......(1)

ANGLE ABC = ANGLE BAC = ANGLE BCA=60 ......PROPERTY......(2)

Now AD Is the angle bisector

Hence , angle BAD = angle CAD = 30

AD IS ALSO PERPENDICULAR TO BC .......property

Now in triangle ADC

Angle ADC = 90

AD = 3

Angle DAC = 30

Hence sin 30 = AD / AC

1/2 = 3/AC

HENCE

AC= 3×2

AC = 6

PERIMETER = 6+6+6

= 18

HENCE SOLVED

I HOPE YOU GET IT !!

10. The principal sanctioned a certain amount to the librarian to purchase some Mathematics books for the school library. She could buy 80 books casting Rs 90 each from the local book seller. There she approached to the publisher who offered her a 20% discount, Find the number of copies of Mathematics books which she could buy from the publisher for the sanctioned money.​

Answer»

ANSWER:

Hey,

If she could buy 80 books costing ₹90 that MEANS she had ₹7200 (as 80*90 is 7200)

Publisher

Discount=20%

IE selling price = 80% * 90

= ₹72

So, if the price of 1 book is 72 then

No. of books she can buy= 7200/72

= 100 books

Thus, she can buy 100 maths books from the publisher

In the adjoining figure, AB=AC=CD,ADC = 35°.Calculate (i)ABC (ii)BEC​

Answer»

Answer:

i) 70

ii)

Step-by-step explanation:

i) in ACD,

since AC = CD (GIVEN)

ERGO angle CDA = angle CAD =  35

Ergo Angle ACD = 180 - (35 + 35)

        Angle ACD = 110

Now,

Angle ACB + Angle ACD = 180 (linear pair)

Ergo Angle ACB = 180 - 110

        Angle ACB = 70

Since AB = AC (Given)

Ergo Angle ABC =Angle ACB = 70

Therefore Angle ABC = 70

it is possible to design a reactangular park of perimeter 80m and area 400m2? If so, find its length and breadth.​

Answer»

ANSWER:

The length of rectangular park is 20 meter

The BREADTH of rectangular park is 20 meter

Step-by-step explanation:

Given as :

The perimeter of rectangular park = 80 meters

∵  perimeter of rectangular park = 2 (length + breadth)

LET The length = L m

breadth = B m

So, perimeter of rectangular park = 2 (L +  B)

Or,  2 (L +  B) = 80 m

Or, L + B = \dfrac{80}{2}

i.e L + B = 40 m                     .........1

Again'

Area rectangular park = 400 m²

Area of rectangular park =A =  Length × Breadth

So, L × B = 400 m²

From eq 1

(40 - B ) × B = 400

Or, 40 B - B² = 400

i.e  B² - 40 B + 400 = 0

Or,  B² - 20 B - 20 B + 400 = 0

Or, B(B - 20) - 20 (B - 20) = 0

Or, (B - 20 ) (B - 20) = 0

∴ Breadth = B = 20 m

From eq 1

L = 40 m -  20 m

i.e Length = 20 m

Hence, The length of rectangular park is 20 meter

And the breadth of rectangular park is 20 meter . Answer
