Answer:
I think it would be 83.0448 or 83º
Step-by-step explanation:
If X is the opposite of your hypotenuse then you would have to do inverse cos [a^2 +b^2 -c^2 all divided by 2ab]
so you would have the inverse cos of [8^2 +16^2 -17^2 divided by 2(8)(16)] which would give you 83º.
I hope this helped a little bit. Im sorry if it's wrong.
The vector v in 2-space of length 3 pointing up at an angle of π/4 measured from the positive x-axis is: (3/√2, 3√2) and The vector w in 3-space of length 1 lying in the yz-plane pointing upward at an angle of 2π/3 measured from the positive y-axis is: (0, -1/2, √3/2).
<h3>Vector</h3>
a. Vector (v)
Vector (v)=v (cos Ф, sin Ф)
V=1 while the counterclockwise angle that is measured from positive x=Ф=π/4
Hence:
Vector=3(cos π/4, sinπ/4)
Vector=(3/√2, 3√2)
b. Vector w:
Vector w=1(0, cos 2π/3, sin2π/3)
Vector w=(0, -1/2, √3/2)
Therefore the vector v in 2-space of length 3 pointing up at an angle of π/4 measured from the positive x-axis is: (3/√2, 3√2) and The vector w in 3-space of length 1 lying in the yz-plane pointing upward at an angle of 2π/3 measured from the positive y-axis is: (0, -1/2, √3/2).

Answer:
2 multiplied by 4. Then add 3, and add 4. Then multiplied by 5.
2 ramps are rectangles so (width of 26 times length of 30) x 2 = 1560 sq in
The top is 24 by 30 = 720 sq in
Add the area of the ramps to the area of the top to get the answer.
