Help i need to understand
mote1985 [20]
Using thereoms/postulates, we know that the 60° angle and the (5z - 85)° angle are congruent

so to first find z..
60 = 5z - 85
145 = 5z
29 = z

now that we know z, we can find x
simply replace the z in (5z - 85) with 29
and add the entire angle to x to equal 180
(supplementary angles)
(5(29) - 85) + x = 180
(145 - 85) + x = 185
60 + x = 185
x = 125


x = 125 \\ z = 29

a person standing near the top of the Eiffel tower(approximately 300.6 meters) notices a car wreck some distance from the tower.
yarga [219]

Answer:

481.06

Step-by-step explanation:

Let's visualise this case in a right angled triangle.

Height = 300.6 m

Angle of depression = Angle of elevation = 32°

So,

\sin(32)  =  \frac{300.6}{hypotenuse}

=  > 0.5299192642 =  \frac{300.6}{hypotenuse}

=  > hypotenuse =  \frac{300.6} {0.5299192642 }

= 567.2562224244 m

Hypotenuse = Line of sight = 567.25 m

Also,

\cos(32)  =  \frac{base}{567.2562224244}

=  > 0.8480480962 =  \frac{base}{567.2562224244}

=  > base = 0.8480480962 \times 567.2562224244 = 481.0605594599

Hence Base = Distance between the spot of accident & the base of the tower = 481.06 m
