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)
Answer: 303 meters
Step-by-step explanation:
The Burji Khalifa is 830 meters in height and the Sears tower is 527 meters in height.
To find out how much higher the Burji Khalifa is than the Sears tower, subtract the height of the Sears tower from the height of the Burji Khalifa:
= 830 - 527
= 303 meters
