Answer:
A. 51°
Step-by-step explanation:
By the theorem of intersecting secants.
One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do

since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get

, which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.

Step-by-step explanation:
On a coordinate plane, a parabola opens up and goes through (negative 3.75, 0), has a vertex at (negative 2, negative 3), and goes through (0, 1).
Answer:
Step-by-step explanation:
1) GH ≅ GH
HF ≅HL
GF ≅ GL
∠FGH =∠LGH
∠GHF = ∠GHL
∠GFH = ∠GLH
3) WX ≅ DC
XY ≅ CY
WY ≅ DY
∠WXY ≅∠DCY
∠XYW≅ ∠CYD
∠XWY ≅∠CDY
