Question

Find the missing part

Answer 1

Try this sin 30º= y/z; so, 1/2=y/z

Answer 2

COULD MAYBE SHOW ME THE WHOLE PROCESS, thats the only way i understand

Answer 3

ok

Answer 4

ok, wait thats not the answer is it

Answer 5

Correcting y=7,5.

Answer 6

or y = 15/2;

Answer 7

In fact you have 3 differente triangles. And now you can get the x value exchange the y fot the valeu 15/2 in this equation; 1/2=y/z;

Answer 8

ok

Answer 9

Is this right?

Answer 10

i guess so

Answer 11

If you look the draw, you may see that a+b= 15 is in fact a hypotenuse. And you can see too that turn around the triangle you will have the sin 30º = x/15.

Answer 12

ok

Answer 13

in fact i kinda got the process, but i wonder if the answer is right i got 15/3
