Answer:
Where's the graph?
Step-by-step explanation:
^^^
To find length BC, we can use
cos 60° = adjacent/hypotenuse
cos 60° = a/12
Answer:
yep ur right dude
Step-by-step explanation:
X = 20
Isolate the variable by dividing each side by factors that don't contain the variable.
x
=
20
Sine( angle ) = opposite leg / hypotenuse
Sin(50) = x/50
X = 50 x sin(50)
X = 16.853 = 16.9 degrees
