we know that
An isosceles triangle has two equal sides and two equal angles
so
KN=NM
∠K=∠M
The line NL bisect the triangle KNM
therefore
Solve for x
<u>Find the measure of angle N</u>
∠N=
substitute the value of x
∠N=
<u>Find the measure of angle K</u>
∠N+∠K+∠M=
remember that
∠K=∠M
∠N+2∠K=
substitute the values and solve for ∠K
∠K=
therefore
<u>the answer is the option</u>
the measure of angle K is
Anser is 111.1
To find The perimeter you just add all the sides together 10.9+10.9+40.3+40.3 equals 111.1
It’s reflected across the origin. Or to the right across the y axis. Then down across the x axis
