PLEASE HELP and also gets chance to follow Answer the following with an explanation to each problem:
a) 1 g m⁻³ = kg cm⁻³
b) 600 m + 40,000 cm = m
c) 10⁴ kg + 10⁸ g = kg
d) 90 kmph + 40 ms⁻¹ + 400 cms⁻¹ = ms⁻¹
e) 10⁴ m² + 10⁹ cm² = m²
f) 60 m³ + 9 × 10⁸ cm³ = m³

∠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.
