Help please am struggling

93°

Step-by-step explanation:

It's given that angle AOC is 87°. BC is a straight line so, angle E=180°-87°=93°

87 degrees put your right hand in an L and that is 90 degrees the it is going down and it says 87 degrees, so it is 87 degrees.

probability for j is 1/4

while

a is 1/6

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
