Answer:
cosA/cosB = 1
Step-by-step explanation:
We know that cos = Adjacent Side/hypothenuse.
Then Cos(A)= AC/AB = 3/4.24 = 0.707
Cos(B) = BC/AB = 3/4.24 = 0.707
Then cosA/cosB = 0.707/0.707 = 1
Answer:
I'm sorry, I can help only with this one x = 20°
Step-by-step explanation:
2x + 5° + 4x + 15° + 2x = 180°
8x = 180° - 5° - 15°
8x = 160°|÷8
x = 20°
1) Answer: 
<u>Explanation:</u>
The equation of an ellipse is:
; where (h, k) is the center, "a" is the x-radius, and "b" is the y-radius.
Center Radius
x-axis: (10 + -10)/2 = 0 10 - 0 = 10
y-axis: (2 + -2)/2 = 0 2 - 0 = 2
Now, input the values into the equation:

2) Answer: 
<u>Explanation:</u>
Vertices are: (0, 1) and (0, -5) ------> x-values are the same, y = 1, -5
Covertices are: (-1, -2) and (1, -2) ----> y-values are the same, x = -1, 1
Center Radius
x-axis: (-1 + 1)/2 = 0 1 - 0 = 1
y-axis: (1 + -5)/2 = -2 1 - (-2) = 3
Now, input the values into the equation:
