Answer:

t α 1 /r ; t = k/r

Step-by-step explanation:

Given that :

Time taken, t varies inverse as rate, r

MATHEMATICALLY,

t α 1 /r

Hence,

t = k/r ;

Where, k is the proportionality constant

Hence, the situation could be expressed as :

t = k/r OR

t α 1 /r

What’s the answer for IJG
Flauer [41]

Answer:

<u>∠IJG = 123° </u>

Step-by-step explanation:

Since AB║CD, EF ║GH, we can use the Corresponding Angles Postulate, for finding the following congruent angles:

∠IKL ≅ ∠EIJ and  ∠EIJ  ≅ ∠GJA

∠GJA and ∠IJG are supplementary, therefore:

∠GJA + ∠IJG = 180°

∠IJG = 180° - 57°

<u>∠IJG = 123°</u>
