Answer 1

120° +30° +z=180°

150° +z =180°

z= 180°-150°

z=30°

Answer 2

missing angle = 30 degrees

Explanation:

all triangles have an interior angle or 180 degrees.

to find the missing angle, just take the know angles and add them together:

120 + 30 = 150

then take the sum and subtract it from 180:

180 - 150 = 30
