Answer 1

k = 73

The sum of the angles in a triangle is 180°

sum the 2 given angles and subtract from 180 for k

k = 180 - (62 + 45 ) = 180 - 107 = 73

Answer 2

a polygon with three side is called triangle.

we know sum of all angle of triangle is $180^{\circ}$

here we are given three angles are

$45^{\circ}62^{\circ}k^{\circ}$

this implis

$45^{\circ}\dotplus 62^{\circ}\dotplus k^{\circ}=180^{\circ} now107^{\circ}+k^{\circ}=180^{\circ}this impliesk^{\circ}=180^{\circ}-107^{\circ}=73^{\circ}$

hence the required angle $k^{\circ}=73^{\circ}$
