Given: MC bisects both ∠ACB and side AB. Based on the given information and the algebraic and geometric properties presented or proven thus far, choose the congruence theorem that could be used to prove the triangles congruent. If it is not possible to prove the triangles are congruent, choose "not possible".

Not possible

Step-by-step explanation:

Given

See attachment for triangle

Required

Determine the congruence of triangles ACM and BCM

From the question, we understand that:

and

Because MC bisects and side AB

However, there are no further information that can prove the congruence of the resulting triangles

Hence, the solution is "not possible"

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
