Question

Suppose there are two vectors u⃗ and v⃗ , where |v⃗ |=16, |u⃗ |=30, and the angle between the vectors is 90∘. What is |u⃗ +v⃗ |?

Answer 1

Use pythagora's theorem!

Answer 2

please rply me exact answer

Answer 3

They build a right triangle and the side lengths of the triangle is the magnitude of each vector

Answer 4

so answer may be 46 but it is replying wrong answer

Answer 5

sorry I went to bed last night.
\[a ^{2}+b ^{2}=c ^{2}\]
\[16^{2}+30^{2}=c ^{2}\]
\[1156=c ^{2}\]
\[\sqrt{1156}=\sqrt{c ^{2}}\]
\[34=c\]
where c is the magnitude of vector U + V
I do not know how you got 46
