Answer 1

a)
∡AOM=∡BON=52°
∡AON=∡BOM=180°-52°=128°

b)
∡BOM+∡BON=2x°+3x°=180°
5x°=180°     x=36°
∡BOM=∡AON=2x°=2×36°=72°        
∡BON=∡AOM=3x°=3×36°=108°

c)
∡AOM+∡BOM=7x°+8x°+30°=180°
15x°+30°=180°
15x°=150°
x°=10°
∡AOM=∡BON=7x°=7×10°=70°
∡BOM=∡AON=8x°+30°=8×10°+30°=80°+30°=110°

d)
∡AON+∡BON=4x°+6x°-20°=180°
10x°-20°=180°
10x°=200°
x°=20°
∡AON=∡BOM=4x°=4×20°=80°
∡BON=∡AOM=6x°-20°=6×20°-20°=120°-20°=100°
