Answer:
BC equals 5
Step-by-step explanation:
they are parallel to each other making them equal sides
If area of a circle can be expressed by the formula A=πr², where r is the radius of a circle. then √A/π is the radius in terms of the area of the circle.
<h3>What is Circle?</h3>
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given,
The area of a circle can be expressed by the formula A=πr²
r is the radius of a circle
We need to find the radius in terms of the area of the circle
A=πr²
Divide both sides by π.
A/π=r²
Now take square root on both the sides
√A/π=r
Hence, √A/π is the radius in terms of the area of the circle.

-5 because 7x-2x=5x then -5-20 =-25 so -25/5=_5
