Answer:
6.4 minutes or 384 seconds
Answer:
∠ 1 = 120°
Step-by-step explanation:
Note that ∠ Q and ∠ R are congruent, that is both 30°, thus
∠ 1 = 180° - (30 + 30)° = 180° - 60° = 120°
I think it may be a 180 degree angle but I wouldnt trust myself so idk
3(x + 4) = 18 + x
3x + 12 = 18 + x
3x - x = 18 - 12
2x = 6
x = 3
