If the two angle of a triangle are measure 30° and 45° . then what is the value of third angle​

Answer»

Answer:

The angle sum property of TRIANGLE says that sum of all 3 angles of any triangle will always be EQUALS to 180°

so,

angle 1 = 30°

angle 2 = 45°

angle 3 = ?

>(Using angle sum property of triangle)

30° +45° + ? = 180°

75° + ? = 180°

? = 180° - 75°

? = 105°

therefore, angle 3 is 105°.
