Answer:
See the proof below
Step-by-step explanation:
For this case we need to proof the following identity:
We need to begin with the definition of tangent:
So we can replace into our formula and we got:
(1)
We have the following identities useful for this case:
If we apply the identities into our equation (1) we got:
(2)
Now we can divide the numerator and denominato from expression (2) by 
and we got this:
And simplifying we got:
And this identity is satisfied for all:
So it's part of a diameter with the 40, so you should have taken 180-40=140 then it should have been set equal to 140. So 22x+8=140 then 22x=132 then 132÷22=6 so x=6
The answer is 30%.... because 50/65 is .3
Answer:
X = 45
Step-by-step explanation:
Answer:
(0, 3)
Step-by-step explanation:
In slope intercept form, the y-intercept is the "b" or, in an example:
y = mx + b
- m is the slope
- b is the y-intercept
In our first equation, the b is 0 (y=-3/2x, there is no +/- b, so it is 0). If we add positive 3 (up 3 units) then the y-intercept will be 3. This, in a point, is shown with (0, 3) because the y-intercept is where the line hits the y-axis when x is 0.
