Laws of Sine just need a way to solve this, I got kicked out of my last tutor and lost the work and can't get it back
Stels [109]

The measurement of angle A = 52 ° .

In question we need to find angle A ,

To find angle A using Law of Sines :

Law of Sine : ( a / sin A ) = ( b / sin B ) = ( c / sin C ) where a , b and c are the sides opposite to angle A , B and C resp. of a triangle .

Applying Law of Sines ,

25 / sin A = 28 / sin 62

sin A = ( 25 * sin 62 ) / 28

sin A = 0.7883

Therefore , angle A = 52 ° .

Hence , the measurement of angle A = 52 ° .
