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 ° .

Answer:
Sarah = 78
Lee = 79
Step-by-step explanation:
98 + 100 + 65 + 78 + 98 + 46 + 100 + 100 + 45 + 50 = 780
780÷10= 78
97 + 67 + 89 + 99 + 100 + 45 + 79 + 89 + 58 + 67 =
790
790÷10=79
Answer:
D.
Step-by-step explanation:
Based on the attached picture we can say that function representing these values would be exponential because the Y values for successive Integer values of X have a common ratio of 16. This can be proven by multiplying each one of the y values by 16, which would give us the next y value in the successive set. For example,
2.5 * 16 = 40
40 * 16 = 640
640 * 16 = 10,240
Meaning that the values have a common ratio of 16, and are increasing exponentially.
Answer:
-1/4
Step-by-step explanation:
-1 1/2 = -3/2
-3/2= -6/4 (common denominator)
-6/4 + 5/4 = -1/4
