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 want to solve the equation:
Using the quadratic formula. The quadratic formula is given by:
In this case, <em>a</em> = 1, <em>b</em> = 2, and <em>c</em> = 7.
Substitute:
Evaluate:
Simplify the square root:
Hence:
Simplify:
Hence, our solutions are:
Our answer is C.
