Answer:

It states that Angle A = 3x B = 3x + 10 and C = 4x -30

We know that A + B + C = 180

Therefore 3x + 3x + 10 + 4x -30 = 180

10x -20 = 180

10x = 200

Therefore, x = 20

Angle C is 4x -30

= 4 * 20 -30

Angle C = 50

Answer is D

Find the value of the csc 40° using your calculator.

kupik [55]

<h2>Hello!</h2>

The answer is:

C. 1.556.

$csc(40\°)}=1.556$

To solve the problem using our calculator we need to set it to "Degree" mode in order to avoid miscalculations.

Also, we need to remember that the cosecant (csc) is the inverse function of the sine, so:

$csc(40\°)=\frac{1}{sin(40\°)} =\frac{1}{0.6427}=1.556$

Hence, the answer is C. 1.556.

Have a nice day!

So you take 2 hours and multiply it by 5 cause you get $5 per hour. Then multiply 6.25 by 5. Add those together to get your answer!! So 5x2= 10. 6.25x5= 31.25. THE ANSWER SHOULD BE 41.25!
