Question

Observe △CBA shown below.
Part 1: Make up an angle measure for angle C and a length for one of the sides (AB, BC, or CA).

Part 2: Use a trigonometric ratio (sine, cosine, or tangent) to solve for one of the other side lengths.

please provide both the ratio and work used to solve for the missing side length. Round your solution to the nearest hundredth.

Answer 1

what did you get for C? and for the side?

Answer 2

Angle C= 45 degrees, Side CA= 60 ft

Answer 3

cosC=BC/AC=>BC=AC*cosC=60*sqrt(2)/2=30sqrt(2)

Answer 4

when you say 'cosC' do you mean cos(45) ? or cos(60) ?

Answer 5

you measured the angle and it was 45,how could it be 60:)

Answer 6

oh haha ohk
