Answer:
is the same as 
by co-function identities
Step-by-step explanation:
Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.
Also recall the co-function identities:
- sin (90° – x) = cos x
- cos (90° – x) = sin x
This means that 
.
Answer:
I think this is the answer! 2x3 + 5x2 - x - 6 let me know if it’s right :)
Step-by-step explanation:
1)
2)
each of other angles measures 82.5 degrees
3)
4)sorry I don't know the last one
You can either write 2.4 as 12/5 ( an improper fraction) or as 2(2/5) (a mixed number).
