Answer:
5 units
Step-by-step explanation:
bcuz it has a dilation of 3 and 3 times 5 equals 15 which is the length of AD
secx=1/cosx
1. To solve this problem you must apply the following proccedure:
2. You have to verify if secx sinx=tanx, so, you have:
3. You know that secx=1/cosx, and tanx=sinx/cosx, therefore:
(secx)(sinx)
(1/cosx)(sinx)
sinx/cosx
tanx
John= greater than or equal to 26 (a >26 with a line under the symbol)
Yes you can assume they are similar because the sides that correspond with one another are half of the big triangles measurements. 16/2=8 12/2=6 etc.
