Question

Find the value of a, b, c

Answer 1

Answer:

a=50

b=c=130

Step-by-step explanation:

a=50°(vertically opposite angles)

c=b=130° (voa,linear pair)

Answer 2

$\tt \: Find \: \: the \: \: value \: \: of \: \: a, b, c$

$\tt \: \huge \fcolorbox{red}{t}{solution}$

==》 50⁰ = a

[ vertically opposite angles]

$\sf\fcolorbox{gold}{t}{theorem - 1}$

==》if two straight line intersect each other the vertically opposite angles are equal

NEXT ,

$\bf \: a \: + \: b = \: 180 ^{0} (linear \: \: pair \: ) \\ \\ \tt \: {50}^{0} + b \: = \: 180 ^{0} \\ \\ \bf \: b = {180}^{0} - {50}^{0} \\ \\ \tt \: b = 130^{0}$

$\sf \: since \ \: : b = {130}^{0} \\ \\ \tt \: c = {130}^{0} (vertically \: \: opposite \: \: angles)$

$\tt \: \huge \fcolorbox{red}{t}{hence}$

$\bf \: a = {50}^{0} \\ \\ \sf \: b = {130}^{0} \\ \\ \bf \: c = {130}^{0}$

$\tt \fcolorbox{green}{f}{points \: to \: remember \: }$

==》linear pair :- Two adjacent angles whose non-common sides are opposite to one another form a linear pair .

==》Vertically opposite angle:-

when two straight lines intersect each other , a pair of angles which have a common vertex but no common side are called vertically opposite angles .
