Tan is equal to sin over cosine so if this is all the info you are given sin.is 3 and cosine is 4. However it is possible term cancel out like sin could be 3/5 and cosine 4/5 which would still give tan 3/4. Actually that is probably what it is to make a 3 4 5 triangle.
To make sine and cos equal the opposite and adjacent sides must be equal. By corresponding angles it is isosceles so b and c must be 45

A person is connecting heat trace cable on pipe at the jobsite. The cable he or she is using is rated 2.5 watts/foot. How many f

The length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.

<h3>What is an ampere circuit?</h3>

Ampere's circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.”

Here we have a cable rating of 120-volt/15-amp so if the 1-ampere circuit means 1 watt per foot cable will be used for the 1-ampere circuit.

A Total of the 15-ampere circuit means 15 watts needed so we are using 2.5 watts per foot.

$\rm Length \ of\ Cable =\dfrac{15}{2.5}=6 \ \ foot$
