By applying tangent rule in ΔACD,
tan(44)° =
tan(44)° =
0.9657 =
0.9657 =
x =
x = 42.15
≈ 42.2 units
Answer:
see explanation
Step-by-step explanation:
Using the rules of exponents
⇔
and
= 1
Substitute the values of x into
x = 0 → = 1 ⇒ a = 1
x = 2 → =
=
, hence
b =
x = 4 → =
=
, hence
c =
The tangent, cosine and sine ratios of angles X & Y in the reduced faction form is 3/4, 4/5 and 3/5 respectively.
<h3>What are the trigonometry ratios?</h3>For a right angle triangle, the trigonometry ratios can be given as,
Here, <em>a</em> is base side<em>, b</em> is perpendicular side and<em> c</em> is the hypotenuse side of the triangle.
In the given triangle, the length of base side<em> </em>is 8 units, perpendicular side is 6 units and hypotenuse side is 10 units.
Thus, the tangent, cosine and sine ratios of angles X & Y are,
Thus, the tangent, cosine and sine ratios of angles X & Y in the reduced faction form is 3/4, 4/5 and 3/5 respectively.
