(is this a question i can ask @trabolic? ) the velocity of a train relative to the ground is represented by the distance from a to b in the diagram. the velocity of a ball thrown inside the train at an angle of 66° relative to the train is represented by the distance from b to c. what is the distance from a to c (the velocity of the ball relative to the ground), correct to two decimal places? assume that all the points in the diagram lie in the same plane. a. 21.14 m/s b. 18.03 m/s c. 17.20 m/s d. 15.00 m/s

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

wait nvm i know the correct answer now its 100%   81 square feet
