Answer:
180 degrees
Step-by-step explanation:
because 52 degrees + 104 degrees + 24 degrees = 180 degrees
In inverese, when x increases, y deceases, when x decreases, y increses
we see that x increases for all choices
therefor the y values of the answer should be decreasing
first one is increasing, wrong
second is decreasing
third is also decreasing
fourth is increasing
look at second and third
remember
xy=k for inverse
so just solve for k for each and see if it is valid
second
1,60
(1)(60)=k
60=k
2,30
(2)(30)=60
60=60
true
therefor this is nswer
2nd option is answer
I have seen this problem before, except it was worded differently. Is this the problem you wished to express?
1+4=5, 2+5=12, 3+6=21, 8+11=?
If so, then your answer is to simply add the last answer to the next problem. If not, then I am afraid I cannot help you.
1+4=5
5+2+5=12
12+3+6=21
21+8+11=40
