Given:

please find the question.

To find:

distance=?

Solution:

point: A(0,0)  \ \ \ \ \ B(80, 0)

Claculating Slop of AC, \tan 60^{\circ} =  \sqrt{3} = 1.732  

Claculating Slop of BC, \tan 104^{\circ} =  - 4.011

Claculating Slop of AD, \tan 125^{\circ} =  - 1.428

Claculating Slop of BD, \tan 157^{\circ} =  - 0.424

When point C intersepts:

\to y= 1.732 x......(a)\\\to y= -4.011(x - 80)......(b)\\

solve equartion (a) and (b):  

\to x_1 = 55.873 \\\to y_1 = 96.772

When point D intersepts:

\to y= -1.428 x......(c)\\\to y= 0.424(x - 80)......(d)\\

solve equartion (c) and (d):  

\to x_1 = 18.315 \\ \to y_1 = -26.154

Calculating diatance:

\bold{D= \sqrt{(y_2-y_1)^2 +(x_2-x_1)^2}}

by putting the value the distance is  "128.535" .
