A counterexample for the expression secФ / tanФ = sinФ is 45°
This is a FALSE statement.
Explanation:
Solving Right-hand side:
SecФ = 1 / CosФ
tanФ = SinФ / CosФ
secФ/tanФ = 1 / CosФ ÷ SinФ / CosФ
secФ/tanФ = 1 / CosФ × CosФ/SinФ
secФ/tanФ = CosФ / SinФCosФ
secФ/tanФ = 1 / SinФ
Hence,
Left-hand side ≠ Right-hand side
The value of CE = 18.3
According to the statement
Here we have given the value of tangents AE = 8 and BC = 3
we have to find the value of CE and
It is given that AE is the tangent to the circle.
Now we make a equation to find the CE then
(8)^2 = 3(x+3)
In this equation the value of AE is 8. and
In this x is the value of CE and BC have value 3.
And the total value of BE becomes the 3(x+3) and 3 is the parts by which BE is formed.
Then solve the equation
64= 3x +9
3x = 64-9
x = 18.3
So, The value of CE = 18.3

ACB = AC + BC
ACB = 122 + 192 = 314
The answer is b. 314 degrees
Answer: 0; -2
Step-by-step explanation:
Data: y-intercept=x and slope=x
Equation=y=-2
Only step, Point out the y-intercept and slope
-2=y-intercept
0=slope
Reason: Since there is no visible slope, the placeholder would be 0 therefore the slope would be 0, -2 is the only number left so that means the only number that can be y-intercept is -2.
That is why the slope is 0 and the y-intercept is -2
I hope this helps!
