Answer 1

a) cos 63 = x/12

b) the missing side is 5.45

Step-by-step explanation:

a) opposite = side opposite the angle given

given angle = 63 degrees

adjacent = base = x

hypotenuse = longest side = 12

Using trigomnometry SOHCAHTOA

To get x, we apply cosine ratio (CAH). This is because we have been given the hypotenuse and we are looking for adjacent

cosine ratio = adjacent/hypotenuse

cos 63 = adjacent/hypotenuse

cos 63 = x/12

b) cos 63 = x/12

12(cos 63) = x

x = 12 (0.45399)

x = 5.44788

To the nearest hundredth, the missing side is 5.45
