The figure shows a vertical flagpole cd. two
straight wires join point c to points a and b on the
ground, where a, d and b are on the same horizontal
line. it is given that anglecad = 40", anglecbd = 30°
and the distance between a and b is 35 m. find the
height of the flagpole, correct to the nearest m

x=6 and x=3

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
