Question

Help me answer missing angles in each question please

Answer 1

All angles must total 180°

1) x = 180° - 45° - 56° 4) a = 180° - 63° - 90°
x = 79° a = 27°

2) z = 180° - 44° - 90° 5) a = 180° - 135°
z = 46° a = 45°

3) x = 180° - 47° - 45° 6) x = 180° - 52° - 90°
x = 88° x = 38°
y = 180° - 133°
y = 47°
