All of them would be correct except for the third option, Angle BCA is not equivalent to Angle DCE.
Answer:
d = -20
Step-by-step explanation:
Simply subtract the 1st 2 numbers together:
d = 5 - (-15) = -20
Answer:
120x4
Step-by-step explanation:
X = 28% * 80
x = 28/100 * 80
x = 28/10 * 8
x = 2.8 * 8
x = 22.4
28% of 80 is 22.4.
Your final name is a. 22.4
P=focal legnth is the distance from the focus to the vertex, which also is the disance from the directix to the vertex
therefor
distance from directix to focus=2 times focal legnth
find distance
horizontal distance
from y=-0.6 to y=2.6, that is distance ot 3 units
3/2=1.5
focal distance=1.5
