Answer:
C. 17.4
Step-by-step explanation:
add all the numbers and then divide
11 + 14 + 15 + 16 + 16 + 18 + 20 + 20 + 22 + 22 = 174
then divide by the amount of numbers there is which is 10.
174/10 = 17.4
If 2 triangles are similar, then the legnths of sides are in proportion
a.
compare 1 side
CB looks about 4/3 as big as SR
so
ABC:TSR=4:3
b. reverse it
3:4
d.
if smaller is 3/4 of bigger then
a=1/2bh
if b and h are 3/4 smaller then
a=1/2(3/4)^2bh
a=1/2bh(9/16)
smaller is 9/16 compared to bigger so
16:9 is ratio
e. ratio is reversed
9:16
