Your answer is D. All of these statements are true.
Answer:
∠B=60°
Step-by-step explanation:
In this right traingle, using angle B, you have the opposite side which is 6√102, and the adjacent side which is 6√34. Using SOHCAHTOA this invlolves TOA so tangent B = OPPOSITE/ADJACENT or tan B = 6√102/6√34. Simplifying gives tan B=√3. You can use your calculator to solve for B by taking the inverse tangent of √3 or you can use the known trig ratios from the unit circle if you have already learned that to find that angle B is 60°
Answer:
A = 36 pi in^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
A = pi (6)^2
A = 36 pi in^2
Answer:
No
Step-by-step explanation:
How to solve :
(a-4)/(a^2+8a+12)*(a^2-2a-48)/(a^2+4a-32)
Factor:
a^2+8a+12 = (a+6)(a+2)
a^2-2a-48 = (a-8)(a+6)
a^2+4a-32 = (a+8)(a-4)
simplify a+6, and a-4
you are left with (a-8)/(a+2)(a+8) = (a-8)/(a^2+10x+16)
4 feet 8 inches
______________________________________________________________
First find how many inches are in 4 feet + 8 inches. There are 12 inches in 1 foot. Multiply 4 x 12 = 48. Add 8 to 48 = 56. Laney's height in inches is 56 inches.
______________________________________________________________
There are 2.54 centimeters in 1 inch. Multiply 56 x 2.54 = 142.24.
______________________________________________________________
Laney's height is 142.24 centimeters.
