sohcahtoa
since we're finding sine, we need the opposite and hypotenuse.
opposite of <A=3, hyp of <A=5.
opp comes before hyp in "soh", so sin<A=3/5
Answer:
if the sum of two angles is 90° they are said to be complementary
If one angle is x
the other should be (90 - x)°
so the complementary angle of x is (90 - x)

Answer:
19 28/33
Step-by-step explanation:
lets work out the whole number parts first:
= 19 + 17 - 16 = 20.
4/12 + 2/11 - 6/9
= 1/3 + 2/11 - 6/9
Find the LCM of the denominators:
3 = 3
11 = 11
9 = 3*3
- so the LCM is 3*3*11 = 99.
So we have:
33/99 + 18/99 - 66/99
= 51/99 - 66/99
= -15/99
= -5/33
So the answer is 20 - 5/33
= 19 28/33
You just had to subtract 5/33 from 20.
