Answer:
DC= 32.3 units
Step-by-step explanation:
Use Pythag theorem to find BC first
15 ^2 + BC ^2 = 22^2 then BC = sqrt 259
Then use the Pythagorean Theorem again to find DC
DC^2 = 28^2 + sqrt(259)^2
DC=32.3

Answer:
12. 6.4
13. 20
Step-by-step explanation:
This is the Pythagorean theorem, which says a^2+b^2=c^2. So for problem 12 we have 4^2+5^2=c^2. Since, 16+25=41, c=sqrt41 which is about 6.4. For problem 13 we have 15^2+b^2=25^2. Since 25^2-15^2=400, b=sqrt400 which is 20. Hope this helps!
Answer:
Step-by-step explanation:
solve the following proportion?
5/10 = 8/w
5 : 10 = 8 : w
w = (10 * 8) : 5
w = 80 : 5
w = 16
----------------------
check
5 : 10 = 8 : 16
0.5 = 0.5
The answer is good
