Answer:

sinα = opposite/hypotenuse

cosα = adjacent/hypotenuse

tanα = opposite/adjacent

tan25 = 19/x

x = 19/tan25

x ≈ 40.75 to nearest hundredth

sin25 = 19/y

y = 19/sin25

y ≈ 44.96 to nearest hundredth

cos51 = x/20

x = 20cos51

x ≈ 12.59 to nearest hundredth

sin51 = y/20

y = 20sin51

y ≈ 15.54 to nearest hundredth

tan12 = 46/x

x = 46/tan12

x ≈ 216.41 to nearest hundredth

sin12 = 46/y

y = 46/sin12

y ≈ 221.25 to nearest hundredth
