We know the opposite side (10) and the adjacent side (7), so we can use tangent to find angle B.  Since tan = opposite side/adjacent side, we can set up this equation: tan(B) = 10/7.  We can get B on its own by making the equation this: [latex]B = tan^{-1} (10/7)[/latex] Now, we plug this into our calculator to get: B = 55°, so angle B is 55°. Let me know if you need any more help!
