Triangle KLM has KL=29​, KM=28​, and LM=22. What is the area of the​ triangle?

by using heron's formula,

semiperemter (s) = sum of all sides / 2

=》

=》

=》

now, we know area =

=》

=》

=》

=》

so, area of triangle = 288.9 or 289 unit²

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
