The answer is A. let me know if you want me to explain.
Answer:
a= 1
b= 3
c= 2
d= 2
e= 6
f= 8. These are the answers for the question. Love from Gauthmath
15 - 36 + 2 = -21 + 2 = -19..... so therefore, its A.
The measure of CA is equal to measure of CB or CA=CB by the Side Angle Side congruence postulate.
<h3>What is a perpendicular line?</h3>
Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other, known as parallel lines.
We have a statement:
a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects.
Consider the line segment AB,
let D be the midpoint of AB, so AD=DB
CD ⊥ AB
The triangles CAD and CBA are congruent from the Side Angle Side congruence postulate:
AD = DB, CD is common and Angle CDA = angle CDB = 90°, as CD ⊥ AB
So CA=CB
Thus, the measure of CA is equal to measure of CB or CA=CB by the Side Angle Side congruence postulate.

1 is a. 2 is b
1) adding two each time ensures you select numbers of the same parity ,(,even or odd)
2) adding one each time selects consecutive numbers
