Answer:

112 degrees.

Step-by-step explanation:

as we know that the three set of forces will form a triangle, by using cosine rule, we can find the required angle.

2*10*8*cos $\alpha$ = $8^{2} +10^{2} -15^{2} = 64+100-225= 164-225=-61$

now, dividing both sides by 2*10*8,

cos $\alpha$ = -61/160

$\alpha$ = 112.4 degrees = 112 ( appox) ( use calculator for this cos inverse function)
