Answer:
83 degrees
Step-by-step explanation:
vertical degrees show that angles across from one another have the same value. All three angles will add up to 180 degrees. Subtract both 56 and 41 from 180 degrees to get a remainder of 83.
If you're finding the value of z, z would equal 13/2 or 6.5

Answer:
51 cm^2
Step-by-step explanation:
To find the area excluding the shaded triangle, first find the area of the whole figure:
12 x 6 = 72cm^2
Now, find the area of the triangle:
(7 x 6) / 2
42/2
21cm^2
Lastly, subtract the shaded area from the whole:
72 - 21 = 51 cm^2
