The answer is 180 if right
The average of the five consecutive numbers ending with b in discuss when expressed in terms of a is; Choice D; a+3.
<h3>What is the average of five consecutive integers ending with b?</h3>
First, since it was given in the task content that the average of six positive consecutive odd integers starting with a is equal to b, it therefore follows that;
(a+a+2+a+4+a+6+a+8+a+10)/6 = b
6b=6a+30
b=a+5
Also, let the average of the consecutive intergers ending with b be denoted by; x.
(b+b-1+b-2+b-3+b-4)/5 = x
=(5b-10)/5
=b–2
The average, x=b – 2 (where b = a-5)
Ultimately, the value of the required average is; = a+5-2 = a+3.

Answer:
1. yes, both triangles sides are congruent
2. yes, they have congruent sides and they have a congruent angle
3. yes, congruent sides and angle
4. yes, 2 congruent angles
5. no, only one congruent angle not enough proof
6. yes, 2 congruent angles
7. no, only one congruent angle not enough proof
8. no, only one congruent side
A=(a(b))/2
surface area and area are the same in 2D shapes
A= (1.5(1.2))/2 =(1.8)/2 = 0.9 m squared
