Answer:
The value of ∅ for the given trigonometrical equation is 60° .
Step-by-step explanation:
Given as :
The Trigonometrical equation
2 cos∅ + 2 = 3
<u>Now, Solving this equation to get the value of ∅</u>
∴ The equation can be written as
2 cos∅ = 3 - 2
or , 2 cos∅ = 1
or , cos∅ =
∴ ∅ =
I.e ∅ = 60°
So,The value of ∅ for the given trigonometrical equation = ∅ = 60°
Hence, The value of ∅ for the given trigonometrical equation is 60° . Answer
X^2-2x-5=(x-1)^2-6
After substituting we get that the domain is:
{-6;-5}
For this case we have the following system of inequalities:
We must verify if the point is a system solution
Inequality 1:
Inequality is not met!
Thus, the given point is not a system solution.
Answer:
The point is not a system solution.
2c-6+9=3x+3+x
2c-6+9=4x+3
2c-6+9=4x+3
+6 +6
2c+9=4x+9
-9 -9
2c=4x
2c/2= 4x/2
C=2x
Answer:
- 3 + x = 21
X = 24
Step-by-step explanation:
- 3 + x = 21
X = 21 + 3
X = 24
