Answer:
Step-by-step explanation:
Tan 145 = - 0.7002
Tan 85 = 11.43
Tan 145 + tan 85 = 10.7298
1 - tan(145)* tan(85) = 9.003
(Tan(145) + Tan(85)) / (9.003)
= 10.73 / 9.003
= 1.1918
I misread the question. If you mean
(Tan145+tan85) /1-tan145*tan85 (brackets are really important here)
then the answer is
Tan(145 + 85)
= Tan(230)
= 1.1918
The equation for any circle centered at the origin with a radius r is the following:

By looking at the picture, we can see that the radius is 5. We can also use the distance formula to find the distance between (0,0) and (-3,-4), and we will also get 5.
Thus, r=5.
This makes the equation:


That should be your answer, let me know if this is confusing in any way.

Answer: 423,5 hours.
Commission is 6.5% since its a percent you want to convert it into a decimal so you want to divide by 100 : 6.5/100=0.065.
now since its a decimal you want to times it by how much she made:
4,800*0.065=312 hopefully this helps.
