Hello,
I am not doing that with sin, cos and pythagorean theorem.
DEFINITION: we call TAN x=sin x / cos x
This means that in a right triangle the tangent of an angle is the ration of opposed side by adjacent side.
11: tan 8°=12.5/d
==>d=12.5/tan 8°=12.5/0.14054...=88.942121...m≈88.9 (m)
12:
tan 28°=h/420
==>h=420*tan 28°=420*0.5317...=223.3179...≈223.3 (m)
It's the 3rd option. All your doing to me, is adding all the numbers straight down. I think you meant to write it like this: 8x² - x - 4
To find the average miles they drove each day, divide the total amount of miles by the number of days they drove.
1246 / 14 = 89
The Tran Family drove an average of 89 miles every day.
Answer: S=28
