If sin 7A = cos 3A, then m∠A is what?

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

i believe so, according to my "strange" way of figuring out weird math problems like this.
