I added a screenshot with the head of the question
Answer:sin (140°)
Explanation:Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.
Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°
Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.
Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)
Hope this helps :)

Answer:
Gross Pay of Erica is $123.75
Step-by-step explanation:
We are given
Earning per hour = $27.5
Total working hours = 51
we can divide the following as
first 40 hours + 6.5hrs after first 40 hours + 4.5 hours of Sunday
No of hours worked pay per hour
first 40 hours $27.5
after 6.5 hours 27.5 + 13.75 = $41.25 ( 1.5times )
Sunday 4.5hr 27.5 * 2 = $55 (double)
total = 51hrs $123.75
so Erica gross pay of the week is $123.75
Answer:
The answer is C, 40.32
Step-by-step explanation:
If you put 6.25 in your calculator times 40.32% you get 2.52. Then you add the 2.52 to 6.25 to get 8.77.
