If you simplify this expression you get 2x 2 -7x -2
Answer:
It is B
Step-by-step explanation:
(c² - 6c) + (7c + 5)
c² is it's own term
-6c + 7c combine to 'c'
5 is it's own term.
So it is c² + c +5
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 ° .
