Answer 1

What i did:

(A) tan30 = 10/b

10/tan30 = 17.32(h)


so now the other side


10/tan60 = 5.77(h)

hypotenuse of triangle ABC = 17.32 + 5.77 = 23.09


(B) sin 30 = b/23.09

sin 30 x 23.09 = 11.54
the shorter leg = 11.54 (b)


(C) a^2 + 11.545^2 = 23.09^2

a^2 + 133.17 = 533.14

a^2 = 533.14 - 133.17

a^2 = 399.97

a = 19.99
to check:
19.99^2 + 11.54^2 = 532.77 or 533

and i think this may be completely wrong...
