Question

A force of 12 N is exerted on a box. The component of this force which acts along the ground has a magnitude of 9.19 N, as shown below.

What is the measure of angle x?

Answer 1

a) 40°

b)26.8°

c) 30°

d) 37.4°

Answer 2

have you studied trigonometry ?

Answer 3

nope

Answer 4

im in geometry right now

Answer 5

ooo...
i think this will be solved by trigonometry
cos0 = adjacent/hypotenuse
0=theta
adjacent is the side which is the nearest to the angle but not the longest
hypotenuse is the longest side of the triangle
since
cos 0 = adjacent/hypotenuse
0 = cos-1 (9.19/12)

Answer 6

how would you get degrees?

Answer 7

the solution should be in degrees

Answer 8

because in physics you are pretending (in a diagramm) that the relation between the two forces (12 N and 9.19 N) is equal on the drawing.

Answer 9

apart your calculator is set to radian meassure

Answer 10

yes

Answer 11

a?

Answer 12

a? don't understand

Answer 13

a) 40°

Answer 14

is that right?

Answer 15

40.01881388739993 right

Answer 16

12cos(x) = 9.19
cos(x) = 9.19/12
x = 40 degrees

Answer 17

i think that's right

Answer 18

but the equation must be \[\cos^{-1} (9.19/12)\]

Answer 19

iam not sure if you are doing the right conversion
