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

but which class are u may know that first

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
