1) 17∠45∘+22∠70∘=

Answer 1

To find the sum or difference of two vectors in polar form, add/subtract their magnitudes and angles. The sum of 17∠45∘ and 22∠70∘ is 39∠115∘.

Step-by-step explanation:

To find the sum or difference of two vectors in polar form, we add/subtract their magnitudes (lengths) and add/subtract their angles. Given the vectors 17√45° and 22√70°, we can find the sum as follows:

Magnitude of sum: 17 + 22 = 39

Angle of sum: 45 + 70 = 115

Therefore, the sum of 17√45° and 22√70° in polar form is 39√115°.
