<h2>Hello!</h2>
The answer is:
C. Cosine is negative in Quadrant III
<h2>
Why?</h2>
Let's discard each given option in order to find the correct:
A. Tangent is negative in Quadrant I: It's false, all functions are positive in Quadrant I (0° to 90°).
B. Sine is negative in Quadrant II: It's false, sine is negative in positive in Quadrant II. Sine function is always positive coming from 90° to 180°.
C. Cosine is negative in Quadrant III. It's true, cosine and sine functions are negative in Quadrant III (180° to 270°), meaning that only tangent and cotangent functions will be positive in Quadrant III.
D. Sine is positive in Quadrant IV: It's false, sine is negative in Quadrant IV. Only cosine and secant functions are positive in Quadrant IV (270° to 360°)
Have a nice day!
Answer:
MN = 48
Step-by-step explanation:
Since AB is a diameter , so it divides MN into 2 equal parts i.e. MO = NO
7x-4 = 6x
7x-6x = 4
x = 4
Now
MN = MO + NO
MN = 7x-4+6x
MN = 7(4)-4+6(4)
MN = 28-4+24
MN = 48
-4x+154 should be the answer
