Answer:
726 feet
Step-by-step explanation:
Object height and shadow length are proportional, so you have ...
(object height)/(shadow length) = (18 ft)/(72 ft) = (dam height)/(2904 ft)
Then the dam height is ...
dam height = (2904 ft)(18/72) = 726 ft
Hoover Dam is 726 feet high.
Since 6x and 5x+15 are both 90 degree angles, they equal each other....
6x = 5x+15 (Subtract 5x from both sides to get x alone)
x=15

Answer:
1/3,-0.3,1.2,4/3,3/2
Step-by-step explanation:
-1/3,-0.3,1.2,4/3,3/2
<u>Statement </u> <u>Reason</u>
1. AB = x + 16 1. Given
BC = 4x + 11
AC = 77
2. AB + BC = AC 2. Segment Addition Postulate
3. x + 16 + 4x + 11 = 77 3. Substitution Property
4. 5x + 27 = 77 4. Simplification <em>(added like terms)</em>
5. 5x = 50 5. Subtraction Property of Equality
6. x = 10 6. Division Property of Equality
7. AB = 10 + 16 7. Substitution Property
8. AB = 26 8. Simplification <em>(added like terms)</em>
