Answer:
15/17
Step-by-step explanation:
Sin=opposite/hypotenuse
SinD=BC/CD=15/17
<u>Examining the question:</u>
We are given the expression:

We know from Basic trigonometry that:


<u>Simplifying the expression:</u>
Replacing these values in the given expression, we get:

Since the denominator of both the values in the denominator is the same:

We know that
=
, using the same property:

and we are done!
Answer:
square's side is 6
triangle's side is 8
Step-by-step explanation:
let the side of the equilateral triangle be x
then the side of the square is x-2
since the perimeters are equal
4(x-2)= 3x
solve for x
x = 8
and
- square's side length is 8-2 = 6
