Katie is twice as old as her sister Mara. The sum of their ages is 24. Find their ages.
Alenkasestr [34]
So k=katie's' age
m=mara's age

k is 2 times as old as m
k=2m

sum is 24
add means sum
k+m=24

so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16

katie=16
mara=8

Given:

\angle a and \angle b are complementary angles.

\angle a=32^\circ

To find:

The measure of \angle b.

Solution:

According to the definition of the complimentary angles, the sum of two complementary angles is always 90 degree.

It is given that, \angle a and \angle b are complementary angles. So,

\angle a+\angle b=90^\circ

32^\circ+\angle b=90^\circ

\angle b=90^\circ-32^\circ

\angle b=58^\circ

Therefore, the measure of \angle b is 58°.
