Help math can u please it explain it .

x = 7° and y = 4°

Solution:

Given JKLM is a cyclic quadrilateral.

∠J = 99°, ∠K = 7x°, ∠L = (11x + y)° and ∠M = 131°

In cyclic quadrilateral, sum of the opposite angles equal to 180°.

m∠K + m∠M = 180°

7x° + 131° = 180°

Subtract 131° from both sides of the equation.

7x° = 49°

Divide by 7 on both sides of the equation.

x = 7°

In cyclic quadrilateral, sum of the opposite angles equal to 180°.

m∠J + m∠L = 180°

99° + (11x + y)° = 180°

99° + 11(7°) + y° = 180°

176° + y° = 180°

Subtract 176° from both sides of the equation.

y = 4°

Hence x = 7° and y = 4°.
