Answer:
C. 41.0, θ = 77.3°
Step-by-step explanation:
The sum is ...
5(8, 4) -3(-3, -4) +8(-5, 1) = (5·8-3(-3)+8(-5), 5·4-3(-4)+8·1)
= (40+9-40, 20+12+8) = (9, 40)
The magnitude is ...
√(9² +40²) = √1681 = 41
The angle is ...
arctan(40/9) ≈ 77.3°
The resultant magnitude and direction is 41∠77.3°.
Answer:
A
Step-by-step explanation:
equation is of the form f(x) - a which implies a translation downwards of a units
I think d)1/56. If not sorry. Hope it is correct!(if it is, can you mark me brainliest please?)

Answer:
45°, 135°
Step-by-step explanation:
The total of the two angles is 1+3 = 4 times the smaller angle. The total is 180°, so the smaller angle is
180°/4 = 45°
The larger angle is 3×45° = 135°
The two angles are 45° and 135°.
