I believe it is a) 22.4 feet. I looked at the comparison between the 6 feet and the width of the lake and a) seemed to make the most sense.
Answer:

Step-by-step explanation:
75 = 11x-2 <u><em>(Corresponding angles are equal)</em></u>
11x -2 = 75
Adding 2 to both sides
11x = 75+2
11x = 77
Dividing both sides by 11
x = 7
Answer: you do the one
Step-by-step explanation:
Yeah
Answer:
40° and 140° (with x = -10)
Step-by-step explanation:
Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180
