Answer:

x=16

Step-by-step explanation:

If the triangles are similar then their sides are in proportion.

Set the proportions 20/(3x+8)=(x-1)/(x-1+27)

solve for x,

cross multiply

20(x+26)=(x-1)(3x+8),

distribute

20x+520= 3x² +8x-3x-8,

combine like terms

3x²-15x-528=0

solve using quadratic formula

x=16 and x= -11 reject because we cannot have negative measurements

A forest ranger stands at the top of a 120 foot fire tower. He spots a fire 900 feet away from the base of the tower. What is th

Answer: $7.6\°$

Step-by-step explanation:

You need to draw a right triangle as the one attached, where $\alpha$ is the angle of elevation from the fire to the top of the fire tower.

You need to use the Inverse trigonometric function Arctangent:

$\alpha= arctan(\frac{opposite}{adjacent})$

Observe the triangle. You can identify that:

$opposite=120\\adjacent=900$

Then, you can substitute values:

$\alpha= arctan(\frac{120}{900})$

Finally, evaluating, you get that the angle of elevation from the fire to the top of the fire tower is the following:

$\alpha =7.59\°$

Rounded to the the nearest tenth of a degree:

$\alpha\approx7.6\°$
