Hope this helps! This is how you do it.
Do 19 x 6 x 2 = 228
then 28 x 19 x 2 = 1064
then 28 x 6 x 2 = 336
<span>then do 228 + 1064 + 336 = 1628</span>
Ok so ratios
john casts a shadow of 180 when he is 180
therefor shadowheight=realheight
320shadowheight=realheight
realheight=320centimeters
The value of cos theta is 2/√29
<h3>Trigonometry identity</h3>
A trigonometry identity are expressions expressed as cosine, tangent, sine.
Given the following trigonometry identity
cot theta = 2/5
1/tan theta = 2/5
tan theta = 5/2
Determine the hypotenuse
hyp² =5^2 + 2^2
hyp² = 25 + 4
hyp = √29
Determine the value of cos theta
cos theta= adj/hyp
cos theta= 2/√29
Hence the value of cos theta is 2/√29
