The dinosaur's tail bones are at the solution point to the system of equations below. –2x – 7y = –250 4x – y = 140 every time you click a point using the cps, the equations below will update. remember, the solution is the point that makes both equations true. –2( 0 ) – 7( 20 ) = -148 x 4( 0 ) – ( 20 ) = -4 x

based on context clues you gave i'm assuming the answer would be c.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
