Answer:

x = 200/3

Step-by-step explanation:

Apply Thales theorem, we have:

80/(2x) = 60/27

Let's simplify both sides:

40/x = 20/9

or

x/40 = 9/20

Multiplying both sides by 40, we have:

(40/40)x = (20/9)*40

Let's simplify one more time:

x = (20*40)/(9)

or

x = 200/3

Hope this helps!

Answer:

$\frac{x^2}{55000^2} - \frac{y^2}{59464^2} =1$

Step-by-step explanation:

the transverse axis is horizontal.

so its a horizontal hyperbola

Center is the origin so center is (0,0)

Equation of horizontal hyperbola is

$\frac{x^2}{a^2} - \frac{y^2}{b^2} =1$

Given a= 55000 and c= 81000

c^2 = a^2 + b^2

81000^2 = 55000^2 + b^2

subtract 55000^2 on both sides

b = sqrt(81000^2 - 55000^2)= 59464.27

now plug in the values

$\frac{x^2}{55000^2} - \frac{y^2}{59464^2} =1$
