We see a right triangle here.
Use the Pythagorean Theorem:
a^2+b^2=c^2
a & b=legs
c=hypotenuse
a^2+15^2=20^2
a^2+225=400
a^2=175
a=13.2287565553
a=13.2
The missing side is 13.2cm

A man standing near a building notices trhat the angle of elevation to the top of the buiilding is 64. he then walks 240 feet fa
trasher [3.6K]
See the picture attached to better understand the problem
 we know that
in the right triangle ABC
tan 64°=AB/AC------> AB=AC*tan 64°-----> AB=x*tan 64°---> equation 1

in the right triangle ABD
tan 43°=AB/DA----> AB=DA*tan 43°---> AB=(240+x)*tan 43°---> equation 2

equate equation 1 and equation 2
x*tan 64°-=(240+x)*tan 43°---->x*tan 64=240*tan 43+x*tan 43
x*[tan 64-tan 43]=240*tan 43-----> x=240*tan 43/[tan 64-tan 43]
x=200.22 ft

AB=x*tan 64----> AB=200.22*tan 64-----> AB=410.51 ft

the answer is
410.51 ft

What is the equation of the trend line?<br> Enter your answers in the boxes.<br><br> K = _J +_
MrRissso [65]
The y-intercept of the trend line is (0,28).  The slope of this line is
         28-0
m = --------- = 2
         14-0

Thus, the equation of the trend line, in variables K and J, is

K = 2J + 28
