Question

if two angles of a triangle are 45° and 65°, than its third angle is​

Answer 1

Answer:

70 degrees

Step-by-step explanation:

Sum of angles in a triangle : 180 degrees

therefore, 45+65 = 110

                 180-110 = 70

Answer 2

Answer:

First Angle = 45°

Second Angle = 65°

Third angle = ?

Sum of all angle of triangle is 180°

First Angle + Second Angle + Third angle = 180°

45° + 65° + third angle = 180°

Third angle = 180 - 110

Third angle = 70°
