Nothing else is given, so for the two triangles to be congruent, the only possible proof is the ASA theorem.
first pairs of angles: 2x+7=x+21 => x=14
second pairs of angles: 8y-4=4y+28 =>y=8
The two triangles share the same side PR
Based on the Angle-Side-Angle Triangle Congruence theorem, these two triangles are congruent with x=14, y=8
(2x+7) +(8y-4) +Q=180 =>85
Answer:
The area of the circle is 28662 M².
Step-by-step explanation:
Given:
Circumference of circle = 600 M.
Now, to find the area of the circle.
So, <em>to get the area we need to find the radius.</em>
By putting the formula of circumference we get the radius:
Let the radius be r.
Circumference = 2πr
(taking the value of π = 3.14.)

Dividing both sides by 6.28 we get:

Now, <em>for getting the area we put the formula:</em>
Area = πr²



So, <u><em>approximately the area of the circle = 28662 M²</em></u>.
Therefore, the area of the circle is 28662 M².
