Question

MEDAL!!!!
15. What are the ratios for sin A and cos A? The diagram is not drawn to scale.
A. sin A=15/17, cos A=8/17
B. sin A =15/18, cos A=8/17
C. sin A= 15/17, cos A=8/15
D. sin A=8/17, cos A=15/17

Answer 1

write them and tell them to draw the diagrams to scale!!
what good are they if they are not drawn to scale? just misleading is all

Answer 2

what is the sine of A

Answer 3

hint, think "opposite over hypotenuse" which is the whole point of this exercise

Answer 4

ok so whats the first step

Answer 5

there is no "step" you just write it
\[\sin(A)=\frac{opposite}{hypotenuse}\]

Answer 6

ok so sin(a) 15/17

Answer 7

yes

Answer 8

ok and cos(a) 8/17

Answer 9

yes

Answer 10

thanks
