Step-by-step explanation:
Zn + 2HCl => ZnCl2 + H2
Moles of Zn = 13g / (65.38g/mol) = 0.198mol
Volume of HCl = 0.396mol / (0.25mol/dm³) = 1.58dm³.
Volume of H2 = 0.198mol * (22.4dm³/mol) = 4.43dm³.

Step-by-step explanation:
1) Opposite angles are the same. Therefore,
2x-20=x+15
2x-x=15+20
x=35
2) Put x back in the equation for angle mhj
2(35)-20=50
