Answer:
Step-by-step explanation:
<u>Given</u>
- m∠ABC = x°
- m∠BCD = 25°
- m∠CDE = 55°
- m∠DEF = 3x°
Add two more parallel lines passing through points C and D.
Consider alternate interior angles formed by the four parallel lines.
<u>The angles between the two middle lines are equal to:</u>
- m∠BCD - m∠ABC = m∠CDE - m∠DEF
<u>Substitute values and solve for x:</u>
- 25 - x = 55 - 3x
- 3x - x = 55 - 25
- 2x = 30
- x = 15
m∠ABC = 15°
Answer:
12
Step-by-step explanation:
Answer: k < 3.5
explanation: < means less than and > means more than and = means equal to so k < (less than) 3.5
1 feet = 12 inches
1 min = 60 s
1 feet/min = 12 in/60 s = 1 in/5 s = 0.2 in/s
