Let A = -2i + j-k and B = i-j- 5k Write down the angle between A and B

FA A B FB Alpha = 34 degrees F_A = 5 kN F_B = 4 kN Find the Angle opposite the resultant force (in degrees).

Hello, can you please solve for angle x and alpha (a). The solution is angle x = 17.62 degrees and angle alpha = 84.9 degrees but I don't understand how to get these values. Thank you.

1- A line 10mm in length inclined at 75 degrees to the x- axis can be represented as, A. will write 0<75 B. will write 0<15 C. will write 10 <15 D. will write 10 <75 2- How will you create a line representing length 15 units at an angle of 30 degrees with respect to the positive direction of the X-axis and the first point of the line is not at the origin? А. 30<15 B. 15<30 С. @30<15 D. @15<30 3- A fillet command is used to produce, A. Sharp corners B. Round corners C. Both of the above D. None of the above 4- Which statement is true about the precedence of lines? A. a hidden line has precedence over a visible line B. a center line has precedence over a visible line C. a visible line has precedence over a center line D. all of the above

Referring to the figure, calculate for the following:a) Component of the 800 N force in the x-direction.b) Component of the 400 N force in the y-direction.c) Component of the 450 N force in the direction of the line of action of the 800 N force.

Two lines in the x-y plane are described by the expressions: Line 1: x + 2y = -6 Line 2: 3x + 4y = 8 Use vector algebra to find the smaller angle between the lines at their intersection point. a. BAB = 10.3° O b. OAB = 13.3° O c. BAB = 31.3° O d. BAB = 30.10°

Convert the following: (a) 400lbft to knm; (b) 6m/s to mi/h; (c) 20lb/in.2 to Pa; and (d) 500slug/in. to kg/m

please include steps.
