Answer:
x=7cm.
Step-by-step explanation:
A=1/2(a+b)h.
63=1/2(6+12)x.
63=1/2(18)x.
63=9×x.
63/9=9×x/9.
7cm=x.
x=7cm.

Answer:
The angle that is supplementary to angle ∠ Z2 is 136°
Step-by-step explanation:
Given as :
∠ Z2 = 44
Let The supplementary to ∠ Z2 = ∠x
∵ For Supplementary angle , measure of Two angles = 180°
Or, ∠x + ∠ Z2 = 180°
Or, ∠x + 44° = 180°
Or, ∠x = 180° - 44°
So, ∠x = 136°
Hence The angle that is supplementary to angle ∠ Z2 is 136° Answer
