maria [59]

Answer: $4004.76\ ft$

Step-by-step explanation:

Given

inclination is $\theta=75^{\circ}$

Mountain is $h=3900\ ft$ high

Cable is tied $x=910\ ft$ from the base of the mountain

From the figure, length of the shortest path is $l$

It is given by using Pythagoras theorem

$\Rightarrow l^2=3900^2+910^2\\\Rightarrow l=\sqrt{(3900)^2+(910)^2}\\\Rightarrow l=4004.76\ ft$

Bruce is 4 times as old as Indy. 6 years ago, Bruce was 6 times as old as Indy. how old is bruce now?

goblinko [34]

4i = b
6(i-6) = b-6

6(i-6) = 4i - 6
6i - 36 = 4i - 6
2i - 36 = -6
2i = 30
i = 15 years old
b = 60 years old

Check:
15 * 4 = 60
9 * 6 = 54 :)
