Answer:
3cm
Step-by-step explanation:
cb is the same length bisector ac, so the answer is <u>3 cm</u>
Answer:
<u><em>A</em></u>
Step-by-step explanation:
<u>a)</u>
<u></u>
<u></u>
<u>8(9) / 9 = 8 x 7 = 56</u>
b)

2(9) * 3 - 12
18 * 3 = 54 - 12 = 42
c)

4(9) - 18 + 12
36 - 18 = 18 + 12 = 30
d)

21 + 24 = 45
Answer:
45 degrees
Step-by-step explanation:
The graph represent a horizontal ellipse with center ,(h,k)=(-1,3)
Length of major axis, 2a =8-(-10) = 18
Therefore, a = 9
And length of minor axis, 2b =5-1 =4
Therefore b=2
The formula that we have to use to find the vertices
(h+-a,k)
(-1+-9,3) = (-1-9,3),(-1+9,3) = (-10,3),(8,3)
