Answer:
d ≈ 60 ft., h ≈ 104 ft.
Step-by-step explanation:
Additionally: angle of depression = 60°
The angle of elevation and the angle of depression are congruent.
Keisha walked 0.96 all together. You see, all you have to do is add them together. As easy as that.
area of OAB = 72 = (1/2) sin (AOB) * OA * OB solve the above for sin(AOB) to find sin(AOB) = 1/2 area of ODC = 288 = (1/2) sin (DOC) * OD * OD Note that sin(DOC) = sin(AOB) = 1/2, OD = 18 + y and OC = 16 + x and substitute in the above to obtain the first equation in x and y 1152 = (18 + y)(16 + x)...

So it must have side length √<span>16 = </span>4 cm<span> and diagonal </span>length 4√2 cm<span>.</span>
J(Jane) + 3 = B(Billy)*2
J + 3 = 7(2)
J + 3 = 14
J = 14-3
J = 11 (Jane is 11)Cheers!
