Answer:

Step-by-step explanation:
b = 4 × 3.5 = 14 cm²
h = 2,1 cm
then



4-2=2
6*2=12
2+12=14
14 is the answer
Answer:
Its the bottom-right one
Step-by-step explanation:
Have a good day
3.5h+10=5.25h-11
21=1.75h
12=h

52=52
Answer:

Step-by-step explanation:
Define a cyclic quadrilateral by a quadrilateral that is circumscribed by a circle. In this case, since the quadrilateral shown is circumscribed by a circle, it is a cyclic quadrilateral.
A property of all cyclic quadrilaterals is that their opposite angles are supplementary, meaning they add up to 180 degrees. Since
and
are opposite angles in the quadrilateral, they must be supplementary. Therefore, we have the equation:
