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.

Answer:
subtracting
Step-by-step explanation:
Answer:
AC = 2.44
Step-by-step explanation:
Reference angle = 26°
Opposite side = AC = ?
Adjacent side = BC = 5
Applying TOA, we have:
Tan 26 = opp/adj
Tan 26 = AC/5
multiply both sides by 5
Tan 26 × 5 = AC
AC = 2.44 (nearest hundredth)
Answer:
B
Step-by-step explanation:
When solving equations, you need to isolate the variable on one side of the equal sign with the constants on the other. In order to do this, it is required to rearrange the equation using inverse operations. These operations can be done using the properties like addition property of equality, subtraction property of equality and multiplication property of equality. Each property states that the operation does not change the equality of the situation. This means both sides of the equation sign remain equal. Use the property when most to your advantage.
4x-28=2x-6 needs the variable x isolated. The best first move is to rearrange the constants by adding 28 to both sides. This is allowed by the addition property of equality.
