Answer:
well when you hear "union" you think 'joined' or 'together' since thats what it means, In a mathmatical set of numbers, union means that both of the sets are necessary for the equation to be true. I'm not sure what the sets are in this problem but in order to get "union" from anything, that means that when you checked for your domains, the values that you got had to be part of both the given sets
#4 .
x + 8 - 8 = 7 - 8
It's "Subtraction property of equality"
It's correct
Answer:
∠AXC = 46°
∠BXC = 23°
Step-by-step explanation:
If XB is the angle bisector of ∠AXC then XB bisects ∠AXC t at X. Hence;
∠AXC = ∠AXB+∠BXC and ∠AXB= ∠BXC
The equation becomes
∠AXC = ∠AXB+∠AXB
∠AXC = 2∠AXB
Given
m∠AXB=23°
Substitute the given angle into the expression above to get ∠AXC since we are not told what to find but we can as well find ∠AXC
∠AXC =2(23)
∠AXC = 46°
<em>Also note that since ∠AXB= ∠BXC,</em> <em>then ∠BXC will be 23°</em>
Perf!!! Thanks for the points
