Answer:
35
Step-by-step explanation:
They are vertical angles which means angles opposite each other will be equal
Answer::
It would be 16 if you are simplifying it.
Answer:
fourth option
Step-by-step explanation:
The mean is calculated as
mean = 
= 
= 
= 23.6 ( to 1 dec. place )
The median is the middle value of the data set. If there is no exact middle then it is the average of the values either side of the middle.
15 16 21 23 25 25 25 39
↑ middle
median = 
= 
= 24
The mode is the value that occurs most often, that is 25
Thus
mean = 23.6 , median = 24 , mode = 25
Answer:
AD is Congruent to BC and it's given, (given just means that it was already said or stated, and you don't need to do the work to find it) Angle DAC would be congruent to angle BAC (if that doesn't work, rearrange them to look like angle CAB). AC would be congruent to DB. Triangle ADC would be congruent to triangle BCD by (since i don't know exactly which way the letters are arranged is would either be SAS or SSA) and that's because you know two of the sides are congruent to each other and one angle.
I tried hard to sketch out what the shape looked like based on the information given, and that's because I need a visual of what the shape looks like. Sorry, this took so long to answer.
