For this case we use the following definition:
sine (x) = (C.O) / (h)
Where,
x: angle
C.O: opposite leg
h: hypotenuse
Substituting values:
sine (C) = (C.O) / (h)
sine (C) = (AB) / (82)
We look for AB by Pythagorean theorem:
AB = root ((82) ^ 2 - (80) ^ 2)
AB = 18
Substituting:
sine (C) = (18) / (82)
Simplifying:
sine (C) = (9) / (41)
Answer:
the ratio is:
sine (C) = (9) / (41)
To simplify the expression we proceed as follows:
<span>d^2+4d+3/d^2-7d-8 + d^2-2d-8/d^2+5d+6
putting like terms together we have:
(d^2+d^2)+(4d-7d-2d+5d)+(3/d^2-8/d^2)+(-8+6)
=2d^2+0d-5/d^2-2
=2d</span>²-5/d²-2
Answer: 2d²-5/d²-2
Answer:
15 yards
Step-by-step explanation:
use pythagoras theorem
a^2 + b^2 = c^2
9^2 + 12 ^2
81 + 144
225
square root
hypoteneuse= 15 yards
3/19 = 0.157...not this one
3/16 = 0.1875...not this one
3/11 = 0.2727 <== this one does
3/8 = 0.375...not this one
