A street lamp weighs 150 N. It is supported by two wires that form an angle of 120 (degrees) with each other. The tensions in the wires are equal.

a) What is the tension in each wire?

b) If the angle is reduced to 90 (degrees) what is the tension in each wire?

The question were asking to compute the tension of each wire were as a street lamp weighs 150n and its supported by two wires that form an angle of 120 degrees with each other. So base on that, the tension would be 2940 N in the first answer and the second is 2078.89 N
