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)
The answer is B. 0
when it’s a straight horizontal line, the slope is always going to be zero. It’s only going to undefined if the line is vertical.
The answer to the question
Answer:
1) yes
2) no
3) yes
4)no
5)no
