Answer:
The value of x is 12.
Step-by-step explanation:
To make the denominators the same we can: Multiply the top and bottom of each fraction by the denominator of the other.

Cross multiply with each other.

The greatest value is 562.71
X = ?, y = ?;
2 x - 70° = x + 30°
2 x - x = 30° + 70°
x = 100°
x + 30° + 5 y = 180°
130° + 5 y = 180°
5 y = 180° - 130°
5 y = 50°
y = 50° : 5
y = 10°
Answer: C ) x = 100, y = 10
