Answer:
(A)
Step-by-step explanation:
To be honest, since all of them are different, as long as you get the first one right, you will get the others right. A is your answer, for the following reasons:
Reflexive Property: The Reflexive property states that the mirrored version of itself will always be congruent with itself. Generally, to make it easier, they will write it opposite (as they did in the given proof):
<em>line</em> AC ≅ <em>line</em> CA
~
(15 minutes/hour) x (1 spot / 1/2 minute) x (24 hour/day) = <u><em>720</em></u> spots/day
Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
Assuming 22 degrees
complement means they add to 90 degrees
22+?=90
minus 22 both sides
?=68
answer would be C
Answer:
107
Step-by-step explanation:
you will add 60 + 32 +15 = 107 that is how i got the answer
