Step-by-step explanation:

1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.

2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)

3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)

4. that means that ΔADB ≅ΔCDB via SSS rule.

5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)

Hope this helps! :)

Answer:

d= 71518 kilometers

Explanation:

A diameter is twice the radius. Here, we can use the formula d=2r (d=diameter r=radius)

If we substitute the formula, we have

d=2(35795)

After multiplying:

d=71518 kilometers

Determine if the sequence is arithmetic. If it is, find the term named in the problem.
Brums [2.3K]

Answer:

a_{39} <em>= 279</em>

Step-by-step explanation:

a_{n} = a_{1} + (n - 1)d

d = a_{2} - a_{1}

~~~~~~~~~

d = - 17 + 25 = - 9 + 17 = - 1 + 9 = 8

a_{39} = - 25 + 8(39 - 1) = 279

a_{39} <em>= 279</em><em> </em>
