a
x = a * cos(b)
x = 11 * cos(33)
x = 10.71785
x = 10.71785 (correct to 5 decimal places)
Find, correct to five decimal places, the length of the side labeled x
a=11cm, b=33 degrees
there is a picture of the triangle, so I'll do my best to recreate it below.. it's a right triangle with "a" as its the hypotenuse

From nikko's diagram you can see that the side marked x is the vertical
side, so
sin33° = x/11
x = 11sin33° = 5.99103
even if the robot's response of 11cos33° would have bee used,
that would have been = 9.22538 , not the one the robot gave
