a diagram is shown, with angels labeled in degrees complete the sentences about the diagram

Answer:
Equation: 5x = 90
x = 18
<LNM = 54degrees
Step-by-step explanation:
From the diagram shown;
<JNK + <KNL + <LNM = 90
x + x + 3x = 90
5x = 90
x = 90/5
x = 18
The equation 5x = 90 can be used to solve for x
Get <LNM = 3x
<LNM = 3(18)
<LNM = 54 degrees
