Question

what is m∠hkj?

m∠hkj = °

Explanation:

Step1: Recall the total angle around a point

The sum of angles around a point (center of the circle, point \( K \)) is \( 360^\circ \). Let \( m\angle HKJ = x \).

Step2: Set up the equation

We know two other angles: \( 150^\circ \) and \( 130^\circ \). So, \( 150^\circ + 130^\circ + x = 360^\circ \).

Step3: Solve for \( x \)

First, calculate \( 150 + 130 = 280 \). Then, \( x = 360 - 280 = 80 \).

Answer:

\( 80^\circ \)
