Refer to the figure below.
Define unit vectors as follows:

in the eastern direction

in the northern direction
Given:
Vectors a and b point due west and south respectively. Therefore

Part (a)

The magnitude is
|-69(√[1² + 1²])| = 69√2 = 97.58.
The direction relative to west is
θ = tan⁻¹ (b/a) = tan⁻¹ 1 = 45° south of west
Answer:
The magnitude of (a + b) is 97.58 or 69√2.
The direction is 45° south of west.
Part (b).

The magnitude is
|69(√(1+1)| = 69√2 = 97.58.
The direction relative to west is
tan⁻¹ (b/a) = 45° north of west.
Answer:
The magnitude of (a-b) is 97.58 or 69√2.
The direction is 45° north of west.
Answer:
B) No
Step-by-step explanation:
They are not similar because if you add all three angles, they add up to 179. Every triangle is supposed to have 180°.
T=224(1.19)
t=$264 18
264.18-224=40.18
19% of 224 is 40.18
