Answer:

Step-by-step explanation:
Given the expression 
Using law of indices: 

Also:13+8=21
Therefore:

Answer:
Resultant force = 70.71067811865 pounds
Step-by-step explanation:
Pythagoras theorem is used to calculate the resultant force since the angles between two wires is 90⁰
Resultant force² = 50² + 50² = 5000
Resultant force = (5000)¹/² = 70.71067811865 pounds
3x+50=6x-10
subtract 3x
50=3x-10
add 10
60=3x
divide by 3
20=x
