Law of sines says
a/sinA=b/sinB=c/SinC
where a,b,c are sides of a triangle and A,B,C are angles respectively.
a/sin45.1=c/sin59.1
(we can find angle C by sum of angles of a triangle is 180.)
a=sin(45.1) x 10.2/sin (59.1)
a=0.708 x 10.2/0.85
a=8.496
a=8.5 units
now u can find b and c sides.
1. 40 units___16 workers
20 units___x= 8 workers
(20*16)/40=8
2. 40 units___16 workers
25 units___x= 10 workers
(25*16)/40=10
3. 40 units___16 workers
100 units___x= 40 workers
(100*16)/40=40

<h2><u>Quadrilateral</u></h2>
<h3>Classify the quadrilateral in as many ways as possible.</h3>
Shown in the figure, all the measurements of each sides is different, so it is only a quadrilateral. Square has four equal sides and angles, rhombus has only four equal sides, and a parallelogram whose opposite sides are parallel.
<u>Answer:</u>
<em>Picture 1 (Rhombus)</em>
<em>Picture </em><em>2</em><em> </em><em>(Square)</em>
<em>Picture 3 (Parallelogram)</em>
<em>Picture 4 (Quadrilateral)</em>
