Step-by-step explanation:
Here
5x+16+7x-3+6x+5 = 180(being sum of triangle)
or, 18x=180-18
or, x= 162/18
so, x = 9
now,
here,
<ACD = <ACB(diagonals of parallelogram bisect eachother)
or, <ACD = 7x-3
or, <ACD = 7×9-3
or, <ACD = 63-3
So, <ACD = 60°
Answer:
The new position of the bird is 1 ft below surface of pond.
Step-by-step explanation:
- Position of water bird after 15ft dive:
11-15= -4ft
- Position of water after rising 3 feet:
-4+3= -1ft
Therefor it id 1ft below the surface of the pond

Step-by-step explanation:
Hope this helps! :3
plz mark as brainliest!
Sorry i wish i knew the answer i’m actually learning that in class but i don’t quite understand it
5. 6√3
6. x = 10√3 y = 30
7. x = 34 y = 17√3
8. 30
9. SinA = 3/5 CosA = 4/5
10. Tan20 = 9/x
Multiply both sides by x to get it on the other side
x(tan20) = 9
Divide 9 by tan20 to get x.
x = 9/tan20
x = 24.7
