Question

Someone can help me to solve this problem
a support cable is anchored 3m from the base of a pole and is attached to the pole 1 m above the ground
a)determine the lenght of the cable to the nearest tenth of a metre
b)find to the nearest degree, what angle does the cable make with the ground

Answer 1

a) 3.2 i forgot how to do b

Answer 2

sorry

Answer 3

is ok thank you

Answer 4

I think I know how to do b:

So this is your "figure" in your mind:



So @muzzammil.raza is talking about the pythagorean theorem:

a^2 + b^2 = c^2

a=length of pole
b=how far away the rope is from the pole
c=length of pole

Now for b.

This involves simple trigonometry

inverse sine of (a/c) (see figure) = Angle A



Subsitute a and c

and you get about

41.810314895778596 degrees

you can round if you want

Answer 5

*c = length of rope

sorry for typo
