In total there are 432 student and 54+27 students that are sick and on a field trip making a total of 81 student not at school so you do 432-81= 351 students in class.
Volume liquid = volume of the cone = 1/3 * pi * r^2 * h = 1/3 *3.14 * 1^2 * 9
= 9.42 in^3
so total value = 2 * 9.42 = $18.84
Angles 6 and 7, because they are alternate along the transversal.
Also angles 1 and 4.
∠1 ≅∠3 = 130º
1) Gathering the data, accordingly to what's been told we can write:
∠1 + ∠50º = 180º <em>Definition of two supplementary angles</em>
∠50 +∠3 = 180º
2) Then we can evaluate:
∠1 + ∠50º = 180º <em>Subtract ∠50º from both sides</em>
∠1 = 180º -50º
∠1 = 130º
∠50 +∠3 = 180º
∠3 = 180º-50º
∠3 = 130º
3) Hence ∠1 ≅∠3 = 130º because the definition of supplementary angles is the same.
