Question

Find the value of x of the triangle. ​

Answer 1

$\bold{Answer: \:\:Opposite\:\: angles\:\: are\:\: always\:\: equal}$

$\bold{So, \:\:the\:\:angle\:\:opposite\:\:to\:\:80^0\:\:is\:\:also\:\:80^0}$

$\bold{A\:\: straight\:\:line \:\:measures\:\:180^0\:\:So,\:\:the\:\:inner\:\:angle\:\:is: 180 - 115 = 65^0}$

$\bold{The\:\:sum\:\:of\:\:all\:\:angles\:\:of\:\:a\:\:triangle\:\:is\:\:180^0}\\\\ \bold{Then\:\: your\:\: answer\:\: is: 180 - 65 - 80= 35^0}$
