How do I solve <br><img src="https://tex.z-dn.net/?f=%20%20%5Csin%28%20a%20%29%20%20%3D%20.8325" id="TexFormula1" title=" \sin(
Serga [27]

Answer:

a=56.4\degree

Step-by-step explanation:

Let a be an acute angle.

To solve: \sin(a)=0.8325, we take the sine inverse of both sides to obtain:

\sin^{-1}(\sin(a))=\sin^{-1}(0.8325)

Recall  composition property of a function and its inverse function.

f^{-1}(f(x))=x

We apply this property to the left hand side to obtain;

a=\sin^{-1}(0.8325)

We now use our scientific calculator to obtain;

a=56.3564115\degree

We round to the nearest tenth to obtain;

a=56.4\degree

This week, Mister Campanello got an increase in his salary of 3%. He worked 3 days at his previous salary of $16/hour. Then, he
Mrac [35]

Answer: Total amount earned is $647.68

Step-by-step explanation:

He worked 3 days at his previous salary of $16/hour. If he works 8 hours per day, then the amount he earned working at the previous salary is

16 × 8 × 3 = $384

This week, Mister Campanello got an increase in his salary of 3%. It means that the amount by which his salary increased is

3/100 × 16 = $0.48

His new salary would be

16 + 0.48 = $16.48

If he worked for 2 days at his new salary, then the amount he earned working at the new salary is

16.48 × 8 × 2 = $263.68

Total amount earned is

384 + 263.68 = $647.68

Two planes are the same altitude. From the airport , one plane is 50 km away in the direction of N°60 E and another is 80 km awa
djverab [1.8K]

9514 1404 393

Answer:

  78.5 km

Step-by-step explanation:

Measured at the airport, the angle between the two planes is ...

  180° -60° -50° = 70°

The law of cosines tells us the distance between the planes is ...

  d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km

The planes are about 78.5 km apart.
