Angola’s is 10 years older than Alex. Mark is 11 years younger than Alex is the total of their ages is 68 how old is the youngest of them

Given:

Angola is 10 years older than Alex.

Mark is 11 years younger than Alex.

Total of their ages = 68 years

To find:

how old is the youngest of them.

Solution:

Let x be the age of Alex.

Age of Angola = 10 years older than Alex

                         = x + 10

Age of Mark = 11 years younger than Alex

                     = x - 11

Total ages = 68

Add 1 on both sides.

x = 23

Age of Alex = 23

Age of Angola = 23 + 10 = 33

Age of Mark = 23 - 11 = 12

Mark is 12 years who is the youngest of them.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
