(ix) - 47° 30'
3. Two angles of a triangle are 72° 53' 51" and 41° 22' 50” respectively. Find the
third angle in radians.
Find the​

Answer 1

Step-by-step explanation:

given angle are 72° 53' 51" = 72.9°

41° 22' 50" = 41.4°

sum of the angles in a triangle =180°

third angle= 180° - 114.3°

we know that 1 radian = 57.15° (approx)

Third angel measure = 2 radians
