A guy wire to a tower makes a 71° angle with level ground. At a point 36 ft farther from the tower than the wire but on the same

lilavasa [31]

The length of the wire is 37.15 ft

<u>Explanation:</u>

The figure is attached for the reference.

tan (71) = $\frac{y}{x}$

tan (36) = $\frac{y}{36+x}$

So,

tan(36) (36 + x) = y

tan(71) = $\frac{tan (36) (36 + x )}{x}$

$2.9 = \frac{0.73 (36 + x)}{x} \\\\2.9 x = 26.28 + 0.73x\\\\2.17x = 26.28\\\\x = 12.11 ft$

Substituting x = 12.11 ft in equation 1:

$tan (71) = \frac{y}{12.11} \\\\2.9 X 12.11 = y\\\\y = 35.119 ft$

Length of the wire, z = $\sqrt{x^2 + y^2}$

So,

$z = \sqrt{(12.11)^2 + (35.119)^2} \\\\z = \sqrt{146.6521 + 1233.3442} \\\\z = 37.15 ft$

Therefore, the length of the wire is 37.15 ft

What are independent and dependent variables?

Nonamiya [84]

I'm pretty sure this doesn't belong in mathematics but this belongs to science. Anyways.. an independent variable is the only variable that is being changed. The dependent variable is what you find out- in other words it is the outcome.
