ANSWER
Given,
AB=5 cm,BC=12 cm
So, AC=
5
2
+12
2
=13
We know that
x=
2
AB+BC−AC
x=
2
5+12−13
x=
2
4
x=2 cm
Hence, this is the answer.
Answer:
x = 68
Step-by-step explanation:
The consecutive angles of a parallelogram are supplementary, sum to 180° , then
69 + 43 + x = 180 , that is
112 + x = 180 ( subtract 112 from both sides )
x = 68
