Answer:
y = 3
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
2(3y + 5) = 28 ( divide both sides by 2 )
3y + 5 = 14 ( subtract 5 from both sides )
3y = 9 ( divide both sides by 3 )
3
The two quads are of similar, and we know that they are of ratio 1:2, thus
3y+5/7 = 2
5.1
you need to work backwards.
so do 17.5 + 8 then divide by 5 to get 5.1
i hope this helps :)
h=3in
A=a+b
2h
Solving forh
h=2A
a+b=2·13.5
3+6=3in
D
