Answer:
AE = 11.76 units
Step-by-step explanation:
For better understanding of the solution, see the attached figure :
Given : E ∈ AB, m∠ABC = m∠ACE, AB = 34 and AC = 20
To find AE :
In ΔABC and ΔACE,
m∠ABC = m∠ACE ( Given )
∠A = ∠A ( Common angle for both the triangles )
By AA postulate of similarity of triangles, ΔABC ~ ΔACE
So, proportion of the corresponding will be equal.
Hence, AE = 11.76 units
Answer:
C.
Step-by-step explanation:
We have been given a function formula . We are asked to find the axis of symmetry for the given function.
We can see that our given function is a parabola in vertex form. We know that vertex from of parabola is , where (h,k) represents vertex of parabola.
Let us convert our given function in vertex form as:
We know that axis of symmetry of a parabola is the equation of x-coordinate of vertex, which in form .
Since the x-coordinate of vertex is , therefore, the axis of symmetry for the given function would be
.
