Answer:
The length of the two pieces are 41 in and 24 in
Step-by-step explanation:
Let
x -----> the length of one piece
y ----> the length of the other piece
we know that
-----> equation A
-----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for y
Find the value of x
therefore
The length of the two pieces are 41 in and 24 in
Since 15/8=1.875, the answer would be #1 because 1.875 is more than 1 but less than 2
Answer:
x = (8-6i)/10
x = (8+6i)/10
Step-by-step explanation:
Slope of perpendicular lines = opposite reciprocal
the slope of y = 2x - 17 is 2 or 2/1.
we using opposite reciprocal
opposite reciprocal a/b is -b/a
2/1 would change into -(1/2)
now, input the value x and y,
and the answer is c. y = -(1/2)x -3

She should navigate at 45° 34' 22.7856" to go to Island C.
Given that Susan is on vacation at a tropical bay that has three islands, and she rents a boat on Island A and plans to navigate to Island C, which is 8 miles away, to determine, based on the figure below, at what angle should she navigate to go to Island C, the following calculation must be carried out, applying the cosine law:
- 11^2 = 8^2 + 15^2 - (2 x 8 x 15) x cos A
- Cos A = (8^2 + 15^2 - 11^2) / (2x8x15)
- A = arc cos (8^2 + 15^2 - 11^2) / (2x8x15)
- A = arc cos (64 + 225 - 121) / 240
- A = arc cos (168 / 240)
- A = arc cos 0.7
- A = 45.572996
Therefore, she should navigate at 45° 34' 22.7856" to go to Island C.
