Angle j40 angle m80 angle in 110 angle l 30 what is the measure of angle n k j a 40° B 67° c 107 degrees B 140°
To find the measure of angle N, we need to use the fact that the sum of the angles in a triangle is always 180 degrees.
From the given information, we know that:
- Angle J = 40 degrees
- Angle M = 80 degrees
- Angle L = 30 degrees
To find Angle N, we can use the equation: Angle N + Angle K + Angle J = 180 degrees
We are given Angle J = 40 degrees, so we can substitute that into the equation: Angle N + Angle K + 40 = 180 degrees.
We don't know the measure of Angle K, so let's work with the other angles to see if we can find it.
Angle M = 180 - (Angle K + Angle N)
80 = 180 - (Angle K + Angle N)
Angle K + Angle N = 100 degrees
Now we can substitute this into the original equation:
Angle N + Angle K + 40 = 180 degrees
Angle N + 100 + 40 = 180 degrees
Angle N = 180 - 140
Angle N = 40 degrees
Therefore, the measure of angle N is 40 degrees.
