we know that
If DF is parallel to GH
then
the measure of the angle EGH must be equal to 70° by corresponding angles
so
<u>Find the measure of the angle EGH </u>
In the triangle EGH
the sum of the internal angles must be equal to 180 degrees
42°+68°+∠EGH=180°
solve for ∠EGH
∠EGH=180-(42+68)
∠EGH=180-110
∠EGH=70°
therefore
The lines DF and GH are parallel
Answer: number three is c. Not 100% positive, but I’m pretty sure
Step-by-step explanation:
8:10 All you need to do is add the : in between
I believe C because 3/4 is 75% a d 5/8 is 62.5%
Yay
so
this is going to be
(x-h)^2=4p(y-k)
(h,k) is the vertex
p is the distance from the vertex to the focus and the vertex to directix
half of the distance between directix and focus is p
if the directix is above the focus, p is negative
if the directix is below the focus, p is positive
so
we see
y=15/8 is the directix
focus is above directix (p is positive)
it is 2/8 or 1/4 above it
so
half of 1/4 is 1/8
p=1/8
the vertex is 1/8 below vertex so it is it at (-4,16/8) or (-4,2)
the equation is
(x-(-4))^2=4(1/8)(y-2) or
(x+4)^2=4(1/8)(y-2) is the equation
