Show what you know: Finding sin, cos, and tan AC20 BC16 AB12

Step-by-step explanation:

12²+16²=144+256=400=20²

so it is a right angled triangle.

let BC bebase and AB=height or perpendicular

AC=hypotenuse

sinC=12/20=3/5=0.6

cosC=16/20=4/5=0.8

tan C=12/16=3/4=0.75

similarly sin A=16/20=4/5=0.8

cos A=12/20=3/5=0.6

tan A=16/12=4/3≈1.33
