X (x-5)=84
${ x}^{2} - 5x = 84 \\$
${x}^{2} - 5x - 84 = 0$

Answer:

x = -9

Step-by-step explanation:

Segment NL is twice the length of midsegment WV.

2WV = NL

2(x+15) = x+21

2x +30 = x +21 . . . . simplify

x = -9 . . . . . . . . . . . . add -30-x

<em>Additional comment</em>

This value of x means the other segments are ...

MN = 12

WV = 6

NL = 12

Diana works in a building that is 130 feet tall. She is outside, looking up at the building at an angle of 37° from her feet to

AveGali [126]

Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/tan 37 = 130/0.7536 = 172.5 feet

Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9

After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
