Given that the sec A = 13/5 and A is in QIV, determine exact value for the sin A.
AysviL [449]

Answer:

The exact value of sin A is opp/hyp = -12/13

Step-by-step explanation:

If A is in Quadrant IV then the "opposite side" is negative and the "adjacent side" is positive.  Since sec A = hyp / adj = 13 / 5 and since opp^2 + adj^2 must add up to hyp^2,   Therefore y = √(hyp^2 - adj^2), or

y = -√(13^2 - 25) = -√144 = 12.

The exact value of sin A is opp/hyp = -12/13

PLZ HELP 25 POINTS Solve for x show your work<br><br>A. x 5 4 6<br><br>B. 5 3 x 4
frosja888 [35]

The two lines start at the same point outside the circle, using the intersecting Secants theorem, When you multiply the two dims for each line together, they are equal

For A:

5 * (5+x) = 6 * (6+4)

25 + 5x = 60

5x = 35

x = 35/5

x = 7

For B:

5 * (5+ 3) = 4 * ( 4+x)

40 = 16 + 4x

4x = 24

x = 24/4

x = 6

Solve the system of equations of equations by graphing on your calculator rounded to 3 decimal spaces
Vanyuwa [196]

Answer:

x=2.333\\y=-1,667  

Step-by-step explanation:

we have

y-x=-4 ----> equation A

2x+y=3 ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both graphs

Using a graphing tool

The intersection point is (2.333,-1.667)

see the attached figure

therefore

The solution is

x=2.333\\y=-1,667
