In a right triangle:
the sine of an angle * length (the hypotenuse) = length (opposite leg)
the cosine of that angle * length (the hypotenuse) = length (adjacent leg)
Using a scientific calculator we find: sin50°=0.766 ; cos50°= 0.643
thus, the legs are:
|opp leg| = sin50°* 7 in= 0.766* 7 in= 5.4 in
|adj leg| = cos50°* 7 in= 0.643* 7 in= 4.5 in
Answer:
5.4, 4.5
