120° is an angle in the second quadrant.
The reference angle is the related acute angle in the first quadrant, that is
reference angle = 180° - 120° = 60° → C
Answer:
See explanation
Step-by-step explanation:
Assuming we want to solve for x in:
Then we factor to get:
Apply the zero product principle to get:
The question is not all that clear, so I assume you are solving for x in the completed quadratic equation.
Answer:
no
Step-by-step explanation:
Answer is 31 +1/4 hours, in other words 31 hours and 15 minutes.
Answer:
56
Step-by-step explanation:
So you just need to find 7 + what is equal to 63. To find this we have to do inverse operation, which means the opposite operation. So, we do 63-7 which is equal to 56. Therefore, the solution to the equation, or x is equal to 56 (C).
Hope this helps !!
