Let the middle point be M.
MDC is a isometric triangle.
∠MDC = MCD = 25°
∠DBC = 180-25-25-35 = 95°
Answer:
-4t-11
Step-by-step explanation:
rearrange the numbers
2t-6t-9+2
Add negative 2
2t-6t-11
2-6
-4t-11
Set components equal:

From this we find:

Substitute and solve system:

The point where they intersect is:
Area is found by multiplying the length by the width.
Length = AB = 12
Height = 9
Area = 12 *9 = 108 units^2
The answer is D.
