Answer:
12.5
Step-by-step explanation:
your welcome
For number 7 because 9 is the number of small triangle and 99 is for the bigger one so you can say 9 * 11 = 99 so 10 * 11 = 110 = x
and for number 8 because the small triangle has the same sides so the bigger one should have too so x = 100 :)))
hope this is helpful
have a nice day

Answer:
d = 3
Step-by-step explanation:
A common difference d means there is the same difference between consecutive terms, that is
5 - 2 = 3
8 - 5 = 3
11 - 8 = 3
Hence there is a common difference of 3
A²+b²=c², a=opposite b=adjacent c=hypotenuse
a=3,c=√34
3²+b²=√34²
9+b²=34
-9 -9
√b²=√25
b=5
