Step-by-step explanation: this is because angles 1 and 3 are the same, so if line y is moved 5 degrees to the right (clockwise), then it expands angles 1 and 3, so you add 5° to the already known 55°. Hope I helped!
∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
Answer:
Step-by-step explanation:
-3x -2 = 19
+3x +3x
-2 = 19 + 3x
-19 -19
-21 = 3x
Divided by 3
-7 = x
