If two angles of a triangle are 45° and 75°, what is the third angle?

The angle sum property of a triangle states that the sum of all three interior angles always equals 180°. So: Third angle = 180° - 45° - 75° = 60°. This is one of the most fundamental properties in geometry. This triangle has angles 45°, 75°, and 60° — since all angles are different, it's a scalene triangle.

If two angles of a triangle are 45° and 75°, what is the third angle?

The correct answer is C. The angle sum property of a triangle states that the sum of all three interior angles always equals 180°. So: Third angle = 180° - 45° - 75° = 60°. This is one of the most fundamental properties in geometry. This triangle has angles 45°, 75°, and 60° — since all angles are different, it's a scalene triangle.

यदि एक त्रिभुज के दो कोण 45° और 75° हैं, तो तीसरा कोण क्या है?

उत्तर: C — त्रिभुज के कोण योग गुणधर्म के अनुसार, तीनों आंतरिक कोणों का योग हमेशा 180° होता है। अतः: तीसरा कोण = 180° - 45° - 75° = 60°। यह ज्यामिति में सबसे मूलभूत गुणधर्मों में से एक है। इस त्रिभुज के कोण 45°, ...
