Let ABCD is a convex quadrilateral, then we draw a diagonal AC which divides the quadrilateral in two triangles.
{tex}\angle \mathrm{A}+\mathrm{B}+\angle \mathrm{C}+\angle \mathrm{D}{/tex}
= {tex}\angle 1+\angle 6+\angle 5+\angle 4+\angle 3+\angle 2{/tex}
= {tex}(\angle 1+\angle 2+\angle 3)+(\angle 4+\angle 5+\angle 6){/tex}
= {tex}180^{\circ}+180^{\circ}{/tex} [By Angle sum property of triangle]
= {tex}360^{\circ}{/tex}
Hence, the sum of measures of the triangles of a convex quadrilateral is {tex}360^{\circ}{/tex}.
Yes, if quadrilateral is not convex then, this property will also be applied.

Let the number to be divided be x
According to question
{tex}\left( { - \frac{{33}}{{16}}} \right) \div x = - \frac{{11}}{4}{/tex}
{tex}x=\;\left(-\frac{33}{16}\right)\div\left(-\frac{11}4\right)=\left(-\frac{33}{16}\right)\times\left(-\frac4{11}\right){/tex}
{tex}x = \frac{3}{4}{/tex}

Rearrange terms
?=30+7?
?=7?+30
Subtract 7? from both sides of the equation
?=7?+30
?−7?=7?+30−7?
−6?=30
x-=-5

Boy cover distance in 2 1/2 hours
he covers by foot = 5km/hr
In 1 hour he complete 5km
he covers distance by bicycle = 10km /hr
In 1 hour he complete = 10 km
total distance 20 km
x/5 + (20-x ) /10 = 5/2
x +20 =25
x = 25-20
x = 5
Hence, the distance covered by foot is 5 km

Multiply 2/3 with reciprocal of 3/5
2/3 multiplied by 5/3
2/3 *5/3=10/15
So simplify it
10/15=2/3( using 5 table)
Therefore answer =2/3

Zero's origins most likely date back to the “fertile crescent” of ancient Mesopotamia. Sumerian scribes used spaces to denote absences in number columns as early as 4,000 years ago, but the first recorded use of a zero-like symbol dates to sometime around the third century B.C. in ancient Babylon.

There are all 10 outcomes of the event. Getting a number less than 6 has five outcomes as there are five numbers (1, 2, 3, 4, and 5 ) less than 6.
So the probability of getting a number less than {tex}6 = \frac{5}{{10}} = \frac{1}{2}{/tex}
