Answer 5

12
/
13
=
asin

Answer 6

i get z=67.38
i get y=22.61

Answer 7

woo hoo!

Answer 8

rounding
the two angles should sum to 90

Answer 9

i think im typing it in wrong i take 12/13=0.923 then i do the asin and that's what i get i did the same thing for y

Answer 10

that's correct, but you sould round your answers so that y + z - 90 exactly.

z = 67.38,
y = 22.62

Answer 11

ooh ok so it would just be 67 an d22

Answer 12

i mean 23

Answer 13

no... 67 + 22 = 89 not 90.
you could do 67 and 23,
or 67.4 and 22.6,
or 67.38 and 22.62,
etc.
