Square root of 64+49-2(8)(7)cos32
gizmo_the_mogwai [7]

Answer:

+4.245

Step-by-step explanation:

Before you can find the square root of x^2, you have to EVALUATE

64+49-2(8)(7)cos32, and THEN take the square root of the result:

64+49-2(8)(7)cos32 = 64 + 49 - 112(0.848) =  113 - 94.981 = 18.019

Then x^2 = 18.019.

Find the square root of 18.019:  It is +4.245.  A negative result here would make no sense.
