BRAINLIEST PLEASE ANSWER FAST THIS IS MY SECOND TIME REPOSTING THIS I WILL GIVE BRAINLIEST!

In the following figure, triangle ABC is a right triangle, and m∠A = 38°. Find the value of n°. Note: the figure is not drawn to scale.
138°
128°
142°
52°
BTW THERE IS NO 132!

Respuesta :

52 degrees

180 degrees is the total “degree value” of a triangle

90 degrees is given because the triangle is a right triangle

38 degrees is given as angle A

180 - 90 - 38 = 52 degrees

Kind note:

I am sure that the triangle you meant was in the image attached. I will find n in the image I attached.

Solution:

We know that:

  • ∠B = 90°
  • ∠A = 38°
  • Sum of interior angles of a triangle = 180°

Step-1: Find ∠C.

  • ∠A + ∠B + ∠C = 180°
  • => 38 + 90 + ∠C = 180°
  • => ∠C + 128 = 180°
  • => ∠C = 180 - 128 = 52

Step-2: Find n.

52 and n are a linear pair.

  • 52 + n = 180
  • => n = 180 - 52
  • => n = 128
