A woman of height 1.4m standing on top of a building 34.6m high views a tree same distance away. She observes that the angle of depression of the the bottom of the tree is 35° and the angle of depression of the top of the tree is 29°. Assume that the building and the tree stand on level ground.

a. Calculate the distance of the woman from the top of the tree measured along her line of sight.

b. Determine the height of the tree.

can someone pleaseee help me, its due in 18 mins

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

i think the answer is d im not sure

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
