In 2 years, i will be twice as old as i was 5 years ago. my little brother is 3 years younger than i am. our baby sister is 2 years younger than he is.

Step-by-step explanation:

let my present age=x

then 2(x-5)=x+2

2x-10=x+2

2x-x=2+10

x=12

my age=12 years

age of brother =12-3=9 years

age of sister= 9-2=7 years.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
