Answer:
C. 47°
Step-by-step explanation:
The angle between the terminal ray of 227° and the nearest x-axis (the negative x-axis) is ...
227° -180° = 47°
The reference angle is 47°.
_____
In mathematical terms the reference angle is the minimum of the angle modulo 180° and the supplement of that angle.
227° modulo 180° = 47°
180° -47° = 133° . . . . supplement of 47°
min(47°, 133°) = 47° . . . the reference angle
Answer:
i dont know cuz i have 30 resets undertale au rpg and im not smart
Step-by-step explanation:
The first thing you should do is write each speed in vector form.
v1: vector water velocity
v2: vector boat speed with respect to water
writing the vectors we have
v1 = (5 * COS (20 * (PI () / 180)) i) + (5 * SENO (20 * (PI () / 180)) j)
v2 = (30 * COS (30 * (PI () / 180)) i) - (30 * SENO (30 * (PI () / 180)) j)
The vector representing the ship's current motion will be given by the sum of vectors v1 and v2
v1 + v2 = (30.67922522 i) + (15.67922522 j)
The fraction 7/12 is greater than the fraction 11/20
