Answer:

The slope of line h is -9/7

Step-by-step explanation:

mathematically, for two lines that are perpendicular to each other, the product of their slopes is equal to -1

say we have two lines l1 and l2, the product of their slopes m1 and m2 is -1

Mathematically;

m1 * m2 = -1

now, m1 here is 7/9 , we now proceed to calculate m2

7/9 * m2 = -1

7m2/9 = -1

7m2 = -9

m2 = -9/7

If triangle RST is within Quadrant 4 and cos R= √3/2, what is the value of cotR

Nesterboy [21]

Answer:

CotR = -√3

Step-by-step explanation:

In the 4th quadrant, sin is negative;

Since Cos R = √3/2,

Adjacent = √3

Hypotenuse = 2

Get the opposite;

opp^2 = 2^2 -(√3)^2

opp^2 = 4 - 3

opp^2 = 1

Opp = 1

Get sinR

Sin R = opp/hyp

SinR= -1/2

CotR = cosR/sinR

CostR = (√3/2)/(-1/2)

CotR = √3/2* -2/1

CotR = -√3
