Answer:
25°
Step-by-step explanation:
In isosceles triangle KNM, NL is a perpendicular bisector of angle KNM.
This means

Since

you have

No, find the measure of angles KNL and LNM:

and the measure of angle KNM is

Angles adjacent to the base of isosceles triangle are congruent. The sum of the measures of all interior angles is 180°, then

Answer:
the answer is x<
−2
/3 y+
2
/3 but it goes on the bottom
Step-by-step explanation:
x = a number
4x - 63 = x
Subtract 4x from both sides.
-63 = -3x
Divide both sides by -3
21 = x
