In the figure, AB = DE and C is the midpoint of both AD and BE.
a. Prove AABC = ADEC.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the answer is 2/54

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
