Answer:
150 °
Step-by-step explanation:
Question says to find about Which of the following angles has a reference angle of 30 °.
We know that reference angle is the smallest angle that the terminal side of a given angle makes with the x-axis.
We will just subtract the given angle 30 ° from 180 ° to get the respective reference angle
180 ° - 30 ° = 150 °
Hence final answer is 150 °
Combine 35 and x . Since the equation can be written in the form y=kx y = k x , y varies directly with x and k . The constant of variation, k , is 35 .
