Answer:
Nw how old is the girl, her mum & her dad?
let x=xmum's age
x+5=dad's age
x/2 =girl's age
x+x+5+x/2=100
3.5x=95
xmum's age=38
dad's age=43
girl's age=19
A=1 b=8 c=8
h = [-8 +-sq root(64 - 4*1*8)] / 2
h = [-8 +-sq root(32)] / 2
h1 = -4 +

Answer:
The answer is B.
Step-by-step explanation:
The pattern seems to be counting by two.
Y = 54.
This is really complicated to explain, but since x is 36 and the angle on the other side of the known angle is also 36, that makes y 54. Each pair of angles has to equal to 90 degrees.
Hope this helps!
