Help with question
i have measured and somewhat labeled the triangle.
Need help with directions 4-6 and filling in the blanks on sheet.
Transcribed Image Text:Procedure 1: Vector Components / Rectangular
Coordinate System
y-dir
Vector Length = 9. 25cm hyp
Angle =_25°
adi onent = _8,35cm
X-dir
y component =
3.9 cm
x component
A¸ = A cos 0 =
cos
Ay = A sin 0 =
sin
OPP
Transcribed Image Text:1• Use a ruler to record the length of the three sides of the triangle in cm.
2 • Use a protractor to record the angle at the base of the triangle.
3. Label the bold vector "hyp" (for hypotenuse). Label the side opposite the
measured angle "opp" (for opposite). Label the remaining side that is next to
(or adjacent to) the angle "adj".
4• Since cos 0 = adj / hyp , calculate what the length of adj should be (hint:
multiply both sides by hyp)
5• Since sin 0 = opp / hyp , calculate what the lengths of opp should be (hint:
multiply both sides by hyp)
6• Confirm that these last two calculations match the length of the sides you
measured on the triangle on the datasheet.
(Please note: if you switch the measured angle of the triangle to the top, then the
labels for the horizontal and vertical sides have to change, and sin and cos would also
switch places)
