Answer 2

$\star\;{\underline{\underline{\sf{\pink{QueStion\;\;:}}}}}$

find x in the given triangle△

$\star\;{\underline{\underline{solution:-}}}$

let's name the triangle as △ABC

△AC= △AB =given

∠B=30°=given

to find x we need to:-

as we know :-

sum of all the angles in a triangle = 180°

so,

30+x+x=180°

x+x=180°-30°

2x=150°

x=$\dfrac{150}{2}$

x=75°

therefore ,

x = 75°
