Answer 2

Given,

Two angles of triangle are of measures $75$ degree and $45$ degree

• Definition of triangle: A plane figure with three straight sides and three angles.
• In a triangle the sum of three angles is equal to $180$ degree.

Let $x$ be the third angle of a triangle

Now,

$x+75+45=180$

$x+120=180$

$x=180-120$

$x=60$

Therefore, the third angle of a triangle is $60$ degrees.
