Tanα=height/distance

tanα=h/d

d=h/tanα  so

d1=h/tanα  and d2=h/tanß

Then the distance between them is:

d=h/tanß-h/tanα, we know that h=1300, α=71.9°, and ß=27.1° so

d=3100/tan27.1-3100/tan71.9 meters

d≈5045 m (to nearest meter)

Answer:

Step-by-step explanation:

tanα=height/distance

tanα=h/d

d=h/tanα  so

d1=h/tanα  and d2=h/tanß

Then the distance between them is:

d=h/tanß-h/tanα, we know that h=1300, α=(90°-71.9°=18,1°), and ß=90°-27.1°=62.9°) so

d=(3100*tan62.9)-(3100*tan18.1) meters

d≈2116 (to nearest meter)

Fudgin [204]

Answer:

<h2><u><em>x=3 or x=−4</em></u></h2>

Step-by-step explanation:

when a number x is added to it's square, the total is 12. find two possible values of x

x+x^2=12

x^2+x=12

x^2+x−12=12−12

x^2+x−12=0

(x−3)(x+4)=0

x−3=0 or x+4=0

x=3 or x=−4

x=3 or x=−4
