Mathematics

$\small\mathfrak\pink{G} \small\mathfrak\purple{i} \small\mathfrak\blue{v} \small\mathfrak\red{e} \small\mathfrak\green{n} \small\mathfrak\orange{:-}\$

∆SUT in which

∠SUT= x

∠TSU= x

∠STU=x-27°

To find:The value of x

$\small\mathfrak\pink{s} \small\mathfrak\purple{o} \small\mathfrak\blue{l} \small\mathfrak\red{u}\small\mathfrak\green{t} \small\mathfrak\orange{i}\small\mathfrak\blue{o} \small\mathfrak\red{n:-}$

According to the angle sum property of a ∆,the sum of all the angles of a ∆ = 180°Hence, ∠SUT+∠TSU+∠STU = 180°x +x +x-27° = 180°3x -27° = 180°3x -27°+27°= 180°+27°3x = 207°x = 207°/3x = 69°

$\huge\mathcal\colorbox{pink}{\color{red}{x =69°}}$

Hope it Helps
