Answer: 50 degrees.
Step-by-step explanation:
To find the measure of the angle Q, you need to follow these steps:
- Knowing that:
You can divide both sides of the equation by -1,360:
- Finally, using the inverse function of the cosine, Arccosine, we get:
To the nearest whole degree, this is:
Csc² x - 1 = cot² x
1/ sin² x - 1 = cot² x
( 1 - sin² x ) / sin² x = cot² x
cos² x / sin² x = cot² x
cot² x = cot² x
Answer: True.

Answer:
C
Step-by-step explanation:
1. Factor a negative one out of the problem.
-1( 7x^2 +5x -18)
2. Factor.
{Factors of 7= 7 &1}
3. (7x ___) (x _____)

5 needs to be postive.
Answer:
20.
m = -52
22.
x=13
24.
a=-90
26.
n=-2
28.
a=9
30.
m=-10
Step-by-step explanation:
20. m/4=-13
m = -13*4 = -52
22. -143=-11x
x=-143/-11 =13
24. -5=a/18
a=-5*18= -90
26. n-8=-10
n=--10+8
n=-2
28. a+11=20
a=20-11
a=9
30. 18+m=8
m=8-18
m=-10
