BARSIC [14]

Answer:  9.97

==============================================

Explanation:

y = distance from the base of the pole to the closest person

y+200 = total horizontal distance

-------------

Focus on the smaller right triangle.

tan(angle) = opposite/adjacent

tan(26) = 55/y

y*tan(26) = 55

y = 55/tan(26)

y = 112.76671 approximately

Make sure your calculator is in degree mode.

--------------

Now move to the larger right triangle

tan(angle) = opposite/adjacent

tan(x) = 55/(y+200)

tan(x) = 55/(112.76671+200)

tan(x) = 55/312.76671

tan(x) = 0.17585

x = arctan(0.17585) same as \tan^{-1}

x = 9.97349

x = 9.97 degrees approximately

If cos ⁡x=−4/5, and 180°
Vladimir [108]

Answer:

180< x < 270 so x is in 3rd quadrant ,hence tan x is positive cos x=-4/5 tan(x/2) = √ {(1 − cos x) / (1 + cos x)) = √ { (1+4/5)/(1–4/5) } =√{ 9/5)/(1/5) } =√9=±3 now ...

The quadrilateral ABCD has area of 58 in2 and diagonal AC = 14.5 in. Find the length of diagonal BD if AC ⊥ BD.
inessss [21]
When the diagonals of a quadrilateral are perpendicular, the area of that quadrilateral is half the product of their lengths.
.. A = (1/2)*d₁*d₂
Substituting the given information, this becomes
.. 58 in² = (1/2)*(14.5 in)*d₂
.. 2*58/14.5 in = d₂ = 8 in

The length of diagonal BD is 8 in.
