<span>Assuming that this is referring to the same image that was posted before with this question, the correct response is 6.22, although this is different for angles. </span>
Angle E=130degrees because those two are congruent. Therefore if you 180-130 you'll get the other angle in the triangle with 70degrees and y. 180-130=50degrees. Then add 50 and 70. 50+70=120degrees. A triangle is supposed to have 180 degrees inside.
180-120=60degrees.
Therefore y=60degrees
Answer:
7.2 units
Step-by-step explanation:
Estimate and Guess
We know that it cannot be 2.9 units long, because it slanted is 6 units long. The closest value to that is 7.2 units.

Explanation:
The equation of a parabola in vertex form is.

Where (
h

9 is in this form
with (

⇒
vertex =

)
the axis of symmetry passes through the vertex is vertical with equation
x
=

← axis of symmetry graph{(y-x^2+10x-16)(y-1000x+5000)=0 [-20, 20, -10, 10]}
