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:
1/2 is the answer because it is rise over run so rise 1 run 2
When you multiply powers, (add) the exponents.
When you divide powers, (subtract) the exponents.
When you raise a power to a power, (multiply) the exponents.
Anything to the zero power equals (1).
When you have a negative exponent, (flip it) and make it (positive).

34) 3/(x^2)
35) 192 * x^5 * y^11
Answer:
F. 6π is the correct answer
As the diameter of the 2nd circle is 2x+3, its radius will be (2x+3)/2 which is equal to x + 1.5
But as it is identical to the 1st circle their radii will be equal.
Therefore, 2x = x + 1.5
Therefore, 2x - x = 1.5
Thus we get that x = 1.5
Therefore, r (radius) = 2x = 2*1.5 = 3
Now we can find the circumfrence by the equation circumference = 2πr
Therefore, circumference = 2*π*3 = 6π
