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)
I believe it would be <span>f(x)=2x-7</span>
108/12 = 9 so when y = 108 x = 9×2 which = 18 so when y =108 x = 18
Answer:
144
Step-by-step explanation:
(100/5) x 4 + ( 4 to the power of 3 ) = 144
Hope that helps you.
