Maria arrived at 8:30
It's can't be told that no one have arrived before her
She registered the times between 8:30 to 9:30 .
She hasn't registered the data of students who came before her .
So it's not a representative sample

Can anyone show me the steps in order solve this problem

STatiana [176]

M∠A = 42° [isosceles triangle]

m∠B = 180 - 42 - 42 = 96° [in a triangle, the three interior angles always add to 180°]

m∠C = 180 - 96 - (x+12)
m∠C = 84 - x - 12
m∠C = 72 - x

2x+9 + 3x-1 + 72-x = 180
4x + 80 = 180
4x = 180 - 80
4x = 100
x = 100/4
x = 25

m∠C = 72 - x = 72 - 25 = 47°

$\boxed{\boxed{\text{ if } \dfrac{a}{b}=\dfrac{c}{d} \text{ then }a\times d=b\times c}}$

$\dfrac{10}{7}=\dfrac{x}{5}\\\\10\times5=7\times x\\50=7x\\7x=50\\\\\boxed{x=\dfrac{50}{7}}$
