Parallel lines e and f are cut by transversal b. What is the value of y?
1 answer:
Answer:
y = 130
Step-by-step explanation:
Those two exterior angles are equal (property of parallel lines)
y is thsupplement of 4x - 14
2x + 18 = 4x - 14 Add 14 to both sides
2x + 18 + 14 = 4x - 14 + 14 Combine like terms
2x + 32 = 4x Subtract 2x from both sides
2x-2x+32=42-2x Combine
32 = 2x Divide by 2
32/2 = x
16 = x
============
4x - 14 =64 - 14 = 50
y = 180 - 50
y = 130

<span>Answer: c
Explanation:-
Given:- Actual height of tower is 1450.
Model height of tower is 24.
To find the ratio of height we divide it (24/1450)
hence the answer is c 12:725</span>
I think is C or D, but I'm not to sure
