Answer:
Step-by-step explanation:
Sum of interior angles of hexagon = 6(180-360/6) = 720°
x = 720-90-150-130-97-120 = 133°
:::::
Sum of interior angles of heptagon = 7(180-360/7) = 900°
3x = 900-147-112-110-125-160 = 246
x = 82°
:::::
Sum of interior angles of pentagon = 5(180-360/5) = 540°
13x = 540-49-33-83 = 375
x = 375/13 ≈ 28.8°
