Step-by-step explanation:

[tex] \angle 4, \:60\degree \:\&\:61\degree[/tex] are straight line angles.

[tex] \therefore \angle \: 4 + 60 \degree + 60 \degree = 180\degree \\ \\ \therefore \: \angle \: 4 = 180\degree - 121\degree \\ \\ \huge \red {\boxed {\therefore \: \angle \: 4 = 59\degree}} [/tex]

Answer:

∠ 4 = 59°

Step-by-step explanation:

q is a straight line, thus the 3 angles sum to 180° , that is

∠ 4 + 60° + 61° = 180°, that is

∠ 4 + 121° = 180° ( subtract 121° from both sides )

∠ 4 = 59°
