Two angle measures in a scalene triangle are 77° and 62°. The measure of the third angle is 41°.
How does an angle form?
An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints.
The angle is the degree of rotation that it will take for the moving side to go from the initial side to the position it is currently on.
The total measure of the inner angles of a shape;
(n-2) x 180°
where n is the number of sides.
\((3-2)180\\1 \times 180\)
180° is the total measure of the inner angles.
To put that as an equation;
180° = 77° + 62° + x°
x = 41°
