Answer: Option A. Line segment A
Step-by-step explanation: we know that
The height of the triangle must be perpendicular to the base of the triangle
so
In this problem
The segment A is perpendicular to the given height
therefore
The base is the line segment A
This congruency thing is all about corresponding sides and angles. In quadrilateral BCDE and OPQR, DE and QR are in corresponding positions. You don't even have to draw them out to see that. Just like you can say that angle B and angle O are corresponding, and side BC is corresponding to side OP. Match them up; that's all there is to it!
Answer:
The answer is 3.1

If we were to convert it into a **FRACTION** the answer would be : 31/10.
And that i an improper fraction, but as a **MIXED NUMBER** : 
All answers would be : 3.1 , 31/10 and 3 1/10
3xy over 8 is the answer go to mathway
and you can find your answer and it shows you how to do it
So I don’t have a step by step answer but I’m pretty sure it’s Area- =2461.76cm2 r= 28 but idk I just looked it up
