Answer:
The relationship between the two is that they are equal.
Step-by-step explanation:
Since y = cosx is a even function, that means that cosx = cos(-x). Therefore, cos 90 degrees = cos -90 degrees.
We can also test this out:
cos 90 = 0
cos -90 = cos 270 = 0
Therefore, this came to the same conclusion as our first solution.
I hope this helps! :)
I think abc is equal to QPR
The figures are similar, so the corresponding sides are proportional.
For example, the ratio of BD to HF could be 2:1 meaning BD is twice as long as HF. We could have BD = 10 and HF = 5 for instance.
The other sides would be in the same proportion to keep the figures similar. So another example would be ND/TH = 2/1
