Answer:
The third choice down
Step-by-step explanation:
Plotting the point (-2, 9) has us in QII. We connect the point to the origin and then drop the altitude to the negative x-axis, creating a right triangle. The side adjacent to the reference angle theta is |-2| and the alltitude (height) is 9. The sin of the angle is found in the side opposite the angle (got it as 9) over the hypotenuse (don't have it). We solve for the hypotenuse using Pythagorean's Theorem:
so
and
Now we can find the sin of theta:
We have to rationalize the denominator now. Multiply the fraction by
Doing that gives us the final
third choice from the top
Answer:
Step-by-step explanation:
The indicated angles are vertical angles since formed by two intersecting lines.
We know the vertical angles are congruent. Use this property to find the value of x and the angle measure
- 6x = 3x + 42
- 6x - 3x = 42
- 3x = 42
- x = 42/3
- x = 14
The angle measure
