Answer:

x=7

Step-by-step explanation:

Since these angles are complementary, they will add up to 90 degrees, so you can set up the equation like so:

8x+5+3x+8=90

First, combine like terms:

(8x+3x)+(5+8)=90

11x+13=90

Then, subtract 13 from both sides:

11x+13(-13)=90(-13)

11x=77

Then divide both sides by 11:

11x(/11)=77(/11)

x=7

7 is your answer

hope this helps!

SCORPION-xisa [38]
See the attached picture to better understand the problem

we know that
in the right triangle ABC
cos 70=adjacent side angle 70/hypotenuse
adjacent side angle 70=BC----> <span>distance between the ladder and the tree trunk
hypotenuse=AC------> 15 ft

cos 70=BC/AC-------> solve for BC
BC=AC*cos 70------> BC=15*cos 70-----> BC=5.13 ft

the answer is
the </span>distance between the ladder and the tree  is 5.13 ft<span>

</span>
