Question

What is the measure of ∠4? Enter your answer in the box.

Answer 1

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°

Answer 2

Step-by-step explanation:

$\angle 4, \:60\degree \:\&\:61\degree$ are straight line angles.

$\therefore \angle \: 4 + 60 \degree + 60 \degree = 180\degree \\ \\ \therefore \: \angle \: 4 = 180\degree - 121\degree \\ \\ \huge \red {\boxed {\therefore \: \angle \: 4 = 59\degree}}$
