134,500 rounded is 13,000
Magnitude of vector V =√(3²+7²) = √58
Hence: U= -3/√58 - 7/√58
OR multiply numerator and denominator by √58
U = - (3√58)/58 i - (7√58)/58 j
The factored form would be (x+3)(x+4) since 4*3 = 12 and 4+3 = 7

Step-by-step explanation:
The distance formula is given by:

We want to find the distance between (a,b) and (x,y).
The center of the habitat is missing in the question.
Assuming the center is (a,b) where a and b are real numbers, then we can use the distance formula to obtain:

For instance if the center of your habitat us (2,-1), then

50 will be the answer. Because one of the angle is exterior so we need to make that angle interior by 180- angle... then we use the method of finding the third side by
180-(<1+<2)
