What is the measurement of angle L​
rusak2 [61]

Measure of angle L is 70 degrees

<h2>Explanation:</h2>

Hello! recall that you need to provide complete questions in order to get good and correct answers. This problem has missing information, however, I'm going to assume that you need the measure of angle L from the figure attached below. In this case, we have a right triangle, so we know the following facts:

  • ∠M = 20° as indicated in the figure
  • ∠N = 90° and this is indicated with the square symbol.
  • ∠L is the unknown angle

From trigonometry we know that for any triangle the sum of the internal angles add up to 180°. So:

∠M + ∠N + ∠L = 180°

∴ 20° + 90° + ∠L = 180°

Isolating ∠L:

∠L = 180° - 20° - 90°

∴ ∠L = 70°
