Answer:
<1 = 140°
Step-by-step explanation:
Measure of interior angles = (n-2) * 180
i.e. TRIANGLE : (3-2)*180 = 180°
Pentagon: (5 - 2) * 180 = 540°
You know every interior angle measure besides <1, so simple subtract the four other interior angles from the total measure of interior angles.
540° = 112° + 92° + 76° + 120° + (<1)
540° - 112° - 92° - 76° - 120° = <1
140° = <1
