Answer:
answer it s 12. just put the value
Option C: 90° is the value of x.
Explanation:
The given expression is for
We need to solve the expression.
Thus, we have,
Subtracting both sides by 4, we have,
Adding both sides by 8 sin x, we get,
Dividing both sides by 10, we have,
Taking on both sides of the equation, we get,
Thus, the value of x is 90°
Hence, Option C is the correct answer.
Answer:
The answer is option 1.
Step-by-step explanation:
In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).
Option 1,
Option 2,
Option 3,
Option 4,
As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.
