Answer:
Step-by-step explanation:
In each case, draw the right triangle which produces the inverse trig value. That is, label the two sides as needed, and calculate the third side.
It should be clear that


sin(2α) = 2 sinα cosα
So,

See what you can do with the others.
Answer:
Graph A: y = (1/2)x - 2
Step-by-step explanation:
2x−4y=8 in slope-intercept form is -4y = -2x + 8, or y = 1/2x - 2
The slope of this line is 1/4 and the y-intercept is -2. This is represented by Graph A.
Answer:
The answer i 9
Step-by-step explanation:
If the ball bounces 2/3 of the height of 9, and a 1/3 of 9 is 3, then 6 is the answer.
1: Identify the angle.
<em>The following angle is a 90.</em>
2: Set up the equation.
<em>x + (3x + 10) = 90</em>
3: Combine like terms.
<em>4x + 10 = 90</em>
4: Solve for x.
<em>4x + 10 = 90</em>
<em> -10 = - 10</em>
<em>--------------------------</em>
<em>4x = 80</em>
<em>------------------</em>
<em>4 4</em>
<em>x = 20</em>
Your answer is x = 20.
