Math Problem Statement

Find the measure of the missing angles in the given geometric figure with a 41° angle and two unknown angles, x and y.

Solution

To find the missing angles xx and yy, we will use a few key geometric principles:

  1. Right Angle Property: The angle marked between the vertical and horizontal lines is a right angle, meaning it equals 90°.

  2. Straight Angle Property: Angles on a straight line sum up to 180°.

Step-by-Step Solution:

  • The given angle of 4141^\circ and angle xx are on a straight line, meaning they are supplementary. Therefore, x+41=180x + 41^\circ = 180^\circ Solving for xx: x=18041=139x = 180^\circ - 41^\circ = 139^\circ

  • Next, angle yy is part of the right angle. Since the right angle sums to 90°, 41+y=9041^\circ + y = 90^\circ Solving for yy: y=9041=49y = 90^\circ - 41^\circ = 49^\circ

Final Answers:

  • x=139x = 139^\circ
  • y=49y = 49^\circ

  1. If the given angle was 3535^\circ, what would be the value of xx and yy?
  2. What is the sum of all angles around a point?
  3. How would the solution change if the right angle was 100100^\circ instead of 9090^\circ?
  4. How can you find an unknown angle if you're given one angle of a right triangle?
  5. What is the relationship between supplementary and complementary angles?

Tip: Always double-check whether the angles involved are forming a straight line (180°) or a right angle (90°).
