ILL MARK BRAINLIST IF YOU GET 8 AND 9 RIGHT (8) Divide and simplify 7/8 divide 14/8 and (9) Multiply and simplify 2 1/3 * -3 1/2 show work

(8): 1/2

(9) -49/6 or -8 1/6

Step-by-step explanation:

(8) 7/8 ÷ 14/8

    7/8*8/14

    1/2

(9) 2 1/3 *-3 1/2

     7/3*-7/2

     -49/6 or -8 1/6

Hope this helps!

mark above answer Brilliantly

thats correct

∠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.
