Question

find the values of x and y in the following figures ​

Answer 1

$\huge \mathcal{ANSWER :-}$

Two sides are equal so it's isosceles triangle,

let's find X,

$\implies \: \bold{x + x + 80 = 180°}$

$\implies \bold{2x + 80 = 180°}$

$\implies \bold{2x = 180 - 80}$

$\implies \bold{2x = 100°}$

$\implies \bold{x = \huge \frac{ \cancel{100} {}^{50} }{ \cancel2} }$

$\huge \red \star \bold{x = 50°}$

let's find Y,

according to the question ,

$\implies \bold{x + 80 = y}$

$\implies \bold{50 + 80 = y}$

$\huge \red \star\bold{ \: y = 130°}$

so,

X = 50°

X = 50°Y = 130°
