The angle is 75.52 degrees

If there is a vector with the form a i + b j, the cosine of the angle between the given vector and the positive direction of the x - axis is calculated as:

cos θ = a/\sqrt{a^{2}+b^{2}  }

So, given the vector i+\sqrt{15 j, the cosine of the angle between the vector and the x-axis is:

cos θ = 0.25

Therefore, the angle θ between the given vector and the positive direction of the x-axis is:

θ = cos-1(0.25) = 75.52

down below

Step-by-step explanation:

straight lines are 180 degrees and you have 2 angles on a line. one of which is 72 and the other is unknown. It is solved for below.

180=72+x\\180-72=72+x-72\\108=x

your missing degree is 108.

i may not be right, if i'm not i am very sorry.
