The two angles of an triangles measure 100 degree and 50 degree . what is the third side measure?

Answer»

Answer:

We know that sum of 3 ANGLES of a triangle is 180°

The 1st ANGLE =100°

The 2nd angle =50 °

Let

3RD angle be =X

Step-by-step explanation:

Sum of all angles of triangle =180°

So,

100 ° + 50° + x = 180°

150° + x = 180°

X = 180° - 150 °

= 30°

:. Hence the 3rd angle = 30°
