Introduction
In geometry, an inscribed quadrilateral is a quadrilateral whose vertices all lie on a single circle. The angles of an inscribed quadrilateral have unique properties that can be used to solve problems and explore mathematical concepts. In this article, we will delve into the world of inscribed quadrilaterals and explore the properties of the angles of quadrilateral JKLM, which is inscribed in a circle.
The Angles of Quadrilateral JKLM
The angles of quadrilateral JKLM are described as follows:
- m ∠J = 95°: This is the measure of angle J, which is one of the angles of the quadrilateral.
- m ∠K = (215 - 4x)°: This is the measure of angle K, which is another angle of the quadrilateral. The measure of angle K is expressed in terms of a variable x.
- m ∠L = (2x + 15)°: This is the measure of angle L, which is the third angle of the quadrilateral. The measure of angle L is also expressed in terms of the variable x.
The Sum of the Angles of a Quadrilateral
The sum of the angles of a quadrilateral is always 360°. This is a fundamental property of quadrilaterals that can be used to solve problems and explore mathematical concepts.
Using the Sum of the Angles to Solve for x
We can use the sum of the angles of the quadrilateral to solve for the variable x. Since the sum of the angles of a quadrilateral is 360°, we can set up the following equation:
m ∠J + m ∠K + m ∠L + m ∠M = 360°
Substituting the measures of the angles, we get:
95° + (215 - 4x)° + (2x + 15)° + m ∠M = 360°
Simplifying the equation, we get:
325 - 2x + m ∠M = 360°
Since the sum of the angles of a quadrilateral is 360°, we know that m ∠M = 360° - (m ∠J + m ∠K + m ∠L). Substituting this expression for m ∠M, we get:
325 - 2x + 360° - (95° + (215 - 4x)° + (2x + 15)°) = 360°
Simplifying the equation, we get:
-2x + 685° - (310° + 4x) = 360°
Combine like terms:
-6x + 375° = 360°
Subtract 375° from both sides:
-6x = -15°
Divide both sides by -6:
x = 2.5°
The Measures of the Angles of Quadrilateral JKLM
Now that we have solved for the variable x, we can find the measures of the angles of quadrilateral JKLM.
- m ∠K = (215 - 4x)°: Substituting x = 2.5°, we get m ∠K = (215 - 4(2.5))° = 205°.
- m ∠L = (2x + 15)°: Substituting x = 2.5°, we get m ∠L = (2(2.5) + 15)° = 30°.

In this article, we explored the properties of the angles of quadrilateral JKLM, which is inscribed in a circle. We used the sum of the angles of a quadrilateral to solve for the variable x and found the measures of the angles of the quadrilateral. This problem demonstrates the importance of using mathematical concepts and properties to solve problems and explore mathematical concepts.
