Question

The measures of the third angle of the triangle.

${90}^{\circ },{10}^{\circ },$ is ${80}^{\circ }$.( Enter 1 if true or 0 otherwise)

Answer 1

Given two angles of the triangle, ${90}^{\circ },{10}^{\circ }$
Let the third angle be $x$
Sum of the angles = 180
$90+10+x=180$
$x=80$
Third angle = ${80}^{\circ }$
