Question

Find x to the nearest tenth. Consult the table above to find the cosine number.

x

Answer 1

x = 1.2/cos(33deg) = 1.4

Answer 2

how did u solve that?

Answer 3

cos(33) = adjacent/hypotenuse
you know that the adjacent side of the triangle has a length 1.2, and the hypotenuse has length x.

the angle is 33, so:

cos(33) = 1.2 / x

cos(33) is just a number, so you can multiply by x on both sides of the equation to get x*cos(33) = 1.2

then just divide both sides by cos(33) to get

x = 1.2/cos(33)

Answer 4

oh thanks :)
