Let {u1,u2,u3} be an orthonormal basis for an inner product space V. If v=au1+bu2+cu3
is so that ∥v∥=42, v is orthogonal to u3, and ⟨v, u2⟩=−42, find the possible values for a, b, and c.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
