Let the adjacent angles of the parallelogram be 2x and 3x.
We know that sum of adjacent angles of a parallelogram is 180o.
⇒ 2x + 3x = 180o
⇒ 5x = 180o
⇒ x = 36o
Therefore, adjacent angles are 2 × 36o = 72o and 3 × 36o = 108o
We know that the opposite angles of a parallelogram are equal.
Thus, the angles of the parallelogram are 72o, 108o, 72o, 108o.

A quadrilateral is a parallelogram if
i)Its opposite sides are equal
ii) its opposite angles are equal
iii) diagonals bisect each other
iv) a pair of opposite sides is equal and parallel.
v) The sum of the adjacent angles should be 180∘
=========================================================
Solution:
i)
if ∠D + ∠B = 180°, a quadrilateral ABCD may or may not be a parallelogram
but it should also fulfilled some conditions which are as:
The sum of the adjacent angles should be 180∘
Opposite angles must be of equal length.
(ii) No, opposite sides should be of same length. Here, opposite sides are of different lengths. AD ≠ BC
(iii) No, opposite angles should be of same measures. Here opposite angles are of different measures. ∠A ≠ ∠C.

Given, x/2 – 1/5 = x/3 + 1/4
⇒ x/2 – x/3 = 1/5 + 1/4
⇒ (3x - 2x)/6 = (4 + 5)/20
⇒ x/6 = 9/20
⇒ x = (9 * 6)/20
⇒x = 54/20
⇒ x = 27/10

Let the digits at tens place and ones place: x and 9−x respectively.
∴ original number =10x+(9−x)
=9x+9
Now Interchange the digits: Digit at ones place and tens place: x and 9−x respectively.
∴ New number: 10(9−x)+x
=90−10x+x
=90−9x
AS per the question
New number = Original number +27
90−9x=9x+9+27
90−9x=9x+36
18x=54
x=54/18
x=3
Digit at tens place ⇒3 and one's place : 6

(x+2)(x+2)
= x ( x + 2) + 2 (x + 2)
= x(x) + x (2) + 2x + 2 (2)
= x2 + 2x + 2x + 4
= x2 + 4x + 4

x-3/x+1=1/2
2 ( x- 3) = 1( x + 1)
2x - 6 = x + 1
2x - x = 1 + 6
x = 7

The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles.
Angle sum of a convex quadrilateral =(4–2)×180⁰=2×180⁰=360⁰=(4–2)×180⁰=2×180⁰=360⁰
Since, quadrilateral, which is not convex, i.e. concave has same number of sides i.e. 4 as a convex quadrilateral have, thus, a quadrilateral which not convex also hold this property. i.e. angle some of a concave quadrilateral is also equal to 360⁰

For every non-zero rational number a/b there exists a rational number b/a such that
a/b × b/a = 1 = b/a × a/b
The rational number b/a is called the multiplicative inverse or reciprocal of a/b and is denoted by (a/b)-1.
The reciprocal of 12 is 1/12
The reciprocal of 5/16 is 16/5.
