Let 3 other angles are x each
-----------------------------------
We know, sum of angles of a quadrilateral = 360
135 + x + x + x = 360
135 + 3x =360
3x = 360 - 135
3x = 225
x = 225/3
x = 75
Measure of other 3 angles = 75 each

Let the ratio be x :-
Sum of angles of a quadrilateral = 360°
=> 7x + 8x + 9x + 12x = 360
=> 15x + 21x = 360
=> 36x = 360
=> x = 360 ÷ 36
=> x = 10
Angles are :-
7x × 10 = 70
8x × 10 = 80
9x × 10 = 90
12x × 10 = 120

Let the number of bottles filled in 5 hours be ‘x’
Hence ratio of bottles filled and time (hours) are in direct proportion.
6/840=5/x
⇒6×x=5×840
⇒x=(5× 840)/6
X= 5× 140= 700 bottles
Hence, the machine will fill 700 bottles in 5 hours.

Given : Volume of cylinder is 6358 cm cube and its height is 28 cm.
To find : Its radius and curved surface area?
Solution :
Volume of the cylinder is
Where, V is the volume = 6358 cm cube
h is the height = 28 cm
r is the radius
Substitute the values,
The radius of the cylinder is 8.5 cm.
The curved surface area of the cylinder is
r=8.5cm , h=28 cm
Substitute the value,
The curved surface area of the cylinder is 1496 centimeter square.

Draw a line segment BC with the help of scale.
Take a compas and feel the radius of 4 cm and draw an arc of 90° which is point D and perpendicular to the point C.
Join DC = 4cm
Similarly, Feel the radius of 4.5 cm and draw an arc which is point A at the another side of line segment BC which is perpendicular to the point B.
Join AB = 4.5 cm
Then join the AD = 6 cm
and hence we can find automatic AC which is 7 cm and diagonal of quadrilateral ABCD.

6p(p – 3) + 1 (p – 3)
= 6p (p) - 6p(3) + 1(p) - 3 (1)
= 6p2 - 18p + p - 3
= 6p2 - 17p - 3

Perimeter of square 1=12cm
a1= side of square 1 = 12/4=3cm
perimeter of square 2 = 16cm
a2=side of square 2 = 16/4=4cm
The sum of the qareas of these two squares =
=
=9+16=25
the area of the larger square, is therefore,25
the side of the larger square=√25=5cm
The perimeter of the larger square=4*5=20cm
∴The perimeter of the required square is 20cm

Let the 3 angles be x, 2x and 3x
Given that x + 3x = 180
4x = 180
x = 180/4 = 45°
So the three angles are 45°, 90° and 135°
and the fourth angle = 360 - (45*90+135) = 360 - 270 = 90°
Yogita Ingle 5 years ago
1x+2x+3x=180°
6x=180°
x=180/6
x=30°
1st angle =30°
2nd angle =2(30°)=60°
3rd angle=3(30°)=90°

Let the CP of first fan be Rs a
CP of second fan = Rs (3120 - a)
Profit on first fan = 36%
SP of first fan = a + 36% of a
= a + 36a / 100
= 136a/100
Loss on second fan = 5%
SP of second fan = (3120 -a) - 5% of (3120-a)
= (3120 -a) - [5(3120 - a) / 100]
According to question
SP of first fan = SP of second fan
136a / 100 = {(312000-100a) - (15600 - 5a)} / 100
=> 136a = 312000 - 100a - 15600 - 5a
=> 241a = 296400
=> a = 1300 approx
CP of first fan = Rs 1300
Cp of second fan = Rs 1820

Let the current age of Rahul and Haroon be 5x and 7x respectively
Four years later their ages become 5x + 4 and 7x + 4 respectively.
According to the question,
5x + 4 +7x + 4 = 56
or 12x + 8 = 56
Transposing 8 to the RHS we get,
12x = 48
Dividing both sides by 12 gives,
x = 48/12 = 4
Thus current age of Rahul = 5×4 = 20
Haroon = 7×4 = 28

Rewrite 9p2
9p2 as (3p)2
Now,
(3p)2−16
Rewrite 16 as 42
(3p)2 − 42
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=3p and b=4
(3p+4)(3p−4)
