A steep mountain is inclined 74 degrees to the horizontal and rises 3400 ft above the surrounding plain. A cable car is to be installed from a point 870 ft from the base to the top of the mountain. Find the shortest length of cable needed. Include appropriate units in your answer.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
