Answer:

Missing Angle = 75 degrees

This answer may not be correct, if it is or is not, please tell me in the comments!

Step-by-step explanation:

The Missing Angle:

All of the angles add up to 180 since it is a triangle, so the equation is:

90 (the box aka right angle) + 15 + (the missing angle) = 180

Then, add 90 + 15 = 105. After that, do:

180 - 105 = 75 degrees (don't forget the label!)

I am so sorry, but unfortunately, I do not know the answer for finding the lengths of the sides x and y.

Answer:

  • 75°, x = 49.69, y = 12.85

Step-by-step explanation:

The missing angle is complementary with given since the triangle is right.

  • 90° - 15° = 75°

Use trigonometry to find x

  • cos 15° = 48/x
  • x = 48/cos 15°
  • x = 49.69 (rounded)

Use Pythagorean to find y

  • [tex]y=\sqrt{49.69^2-48^2} =12.85[/tex] rounded
