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
A and D are both correct answers

Answer:

Step-by-step explanation:
You need to remember the following equation:

Where a and b is the lengths of the two sides and c is the hypotenuse.
So simply plug these values into this:

36 + 49 = h^2
36 + 49 = 85
So the hypotenuse is the square root of 85:

B, 4% .
Find this by using the Interest Formula:
I = P X R X T
I = 7500 X .OO4 X 3
I = 900
