Question

If the exterior angle of triangle is ${110}^o$ and its. Dpposite interior angle are equal. Find all angle of triangle

Answer 1

Let interior opposites angles be $x$

${110}^{\circ }=x+x$

$x={55}^{\circ }$

angle of triangle interior to ${110}^{\circ }={180}^{\circ }-{110}^{\circ }={70}^{\circ }$

So, the angles of triangle ${55}^{\circ },{55}^{\circ },{70}^{\circ }$
