Answer:
4.05 meters or 405 cm
Step-by-step explanation:
The equation to use is
(x - 330) x 5 = x - 30
330 is equal to 3.30 meters.
Then solve the equation.
(X - 330) x 5 = x - 30
5x - 1650 = x - 30
-x
4x - 1650 = -30
+1650 + 1650
4x = 1620
/4 /4
X = 405cm

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°
