As b is RIGHT angle then 5,12,13 is a PYTHAGOREAN triplet then 13 is hypotenuse and sin c WOULD be ab/ac which is 5/13

D.
1)
ONE necklace=28 shells

therefore,
number of necklace that can be MADE=112/28
=4

4 necklace can be made with 112 shells


2)
a)
LADOOS in one packet=4
packets needed to pack 80 ladoos=80/4
=20

b)
if he packs 20 ladoos in one packet then,

number of packets required=80/20
=4

By applying Unitary method,
Cost of 1 litre = Rs. 72/-
=>Cost of 21/2 litre = 72 × 2 ÷ 21 = Rs. 6.857142857143.

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐

MOTHER EXPRESSION : (a-5)²-(a-8)²

SOLUTION :

(a-5)²-(a-8)²

= (a-5+a-8) (a-5-a+8) [USING, a²-b² = (a+b) (a-b)]

= 3 (2a-13)

= 6a - 39

➡ So, the required answer is (6a-39).

Using heron's FORMULA I find the AREA of the TRIANGLE.

L=b+2
area=l*b
528=(b+2)b
528=2b+b^2
b^2+2b-528=0
b^2+24b-22b-528=0
b(b+24)-22(b+24)=0
(b+24)(b-22)=0
b=-24 & 22
if BREADTH is -24 then length=-24+2=-22
if breadth is 22 then length =22+2=24

Hi MATE!!!


Let the sides be 4x , 5x and 6x

Given. 6x+5x+4x = 150


x = 10cm


So, the sides are 60cm,50cm and 40cm


It's area can be calculated by using HERON's FORMULA. √s(s-a)(s-b)(s-c)

s = 150/2

s = 75. a = 60. b = 50. and. c = 40



Area = 992.15cm²

I ) If the slopes of TWO lines

are equal then the lines

are parallel .

ii ) If a1x + b1y + C1 = 0,

and a2x + B2Y + C2 = 0

are two system of

linear equations ,

( A1 ≠ 0 , a2 ≠ 0 )

if a1/a2 = b1/b2 then

these lines are parallel .

And then DIVIDE 33 by 100 then U will get UR ans

area of parallelogram= 320 CM^2

altitude = 16 cm

area= b * h

= 320= b*16

= b=320/16

= b= 20 cm

ans - the BASE of parallelogram is 20 cm

Let the BASE angles be x , x.

given , VERTEX ANGLE = 50°

sum of all the interior angles of isosceles triangle

= 180°

x + x + 50° = 180°

2x = 130° => x = 65°

since, the base angles of isosceles triangle are equal.

so then x = x = 65°

Therefore,

base angles are x = 65° , x = 65°

12a^2 + 2a - 4

= 12a^2 + 8A - 6A - 4

= 4a( 3a + 2) - 2 (3a +2)

= (4a - 2) (3a +2)

9x² - 3x - 20                                                  PRODUCT(the coefficient of the first term by the constant) = 180

                                                                      sum (coefficient of X) = 3

∴ by splitting middle term method,

9x² - (15x + 12X) - 20

9x² - 15x +12x -20

3x (3x - 5) + 4 (3x - 5)

(3x +4) (3x - 5)

3x + 4 = 0 or 3x -5 = 0

3x = -4 or 3x = 5

∴ x = -4/3 or x = 5/3

Solution :

diameter of the CIRCLE ( d ) = 9.8 m

Area of the circle ( A ) = π( d²/4 )

= ( 22/7 ) × ( 9.8 m )²/4

= ( 22 × 9.8 × 9.8 )/( 7 × 4 )

= 75.46 m²

Therefore ,

Area of the circle ( A ) = 75.46 m²
