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:
the value of x is 31 degrees
To determine the factor pairs for the number 30, simply find out the smallest set of numbers that will multiply to give 30, you would need to break down composite numbers to do this.
30 = 6 • 5 = 2 • 3 • 5.
These all are prime numbers that when multiplied together equals 30.
28 is the answer rrrrrrrrrrrr
18 = .75x
/.75 /.75 (divide both sides by .75 to isolate x)
24 = x

Hope this helps!
