Find the following angle measures. mEAD = ° mCAB = °
2 answers:
<u>Part 1)</u> Find m∠EAD
we know that
m∠EAD+m∠DAF+m∠BAF= ----> by supplementary angles
solve for m∠EAD
m∠EAD=-(m∠DAF+m∠BAF)
in this problem we have
m∠DAF=
m∠BAF=
substitute in the formula above
m∠EAD=
therefore
<u>the answer part 1) is </u>
m∠EAD=
<u>Part 2)</u> Find m∠CAB
we know that
m∠CAB+m∠BAF= --------> by supplementary angles
solve for m∠CAB
m∠CAB=-m∠BAF
in this problem we have
m∠BAF=
substitute in the formula above
m∠CAB=
therefore
<u>the answer part 2) is</u>
m∠CAB=

Answer:
is the the equation of parabola that has vertex (9,7) and passes through point (3,8).
Step-by-step explanation:
To solve this you need to use the vertex form of the equation of a parabola which is
Where (h, k) are the coordinates of the vertex.
So, h = 9 and k =7
And one set of points on the graph
x = 3, y = 8
Solving the formula for .
To create a general formula for the parabola you would put in the values for a, h, and k and then simplify.
Therefore, is the the equation of parabola that has vertex (9,7) and passes through point (3,8).
The graph is also attached.
