Answer:
x = 25
Step-by-step explanation:
1. Due to the fact that Angle F and angle G are complementary, 2x + 10 + 30 = 90.
2. Solve this equation: 2x + 10 + 30 = 90
Add 10 and 30
2x + 10 + 30 = 90
2x + 40 = 90
3. Subtract 40 from 90
2x + 40 = 90
2x = 90 - 40
2x = 50
4. Divide 2 from 50
x = 50/2
x = 25
