there are 5 pics with multiple questions inside them if you do finish this one the will be more on my questions list on my profile

15) choice 1

16) choice 4, 72 degrees

17) choice 3) translation

18) choice 3, never

19) choice 3) 2

20) choice 3

21) acute triangle, at least one angle less than 90 degrees

Step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

answer: it is 1: 47 pm
