[1] First, remember that the sum of the angles in a triangle must add up to 180*.
[2] We are told two of the angles, 44* and 66*, but we are missing the third.
[3] Combining [1] and [2], we know that 44* + 66* + ? = 180*. In other words,
110* + ? = 180*
so,
? = 70*
The missing angle 3 is equal to 70 degrees.
Answer:
Inverse = (arcos x) / 2.
Step-by-step explanation:
y = cos 2x
2x= arcos y
x = (arcos y) / 2.
Inverse = (arcos x) / 2.
Answer:
B.) 140 is your answer for your problem
-6x^4y^5-15x^3y^2+9x^2y^3
The GCF OF -6, -15, & 9, is -3
The GCF OF x's is x^2
The GCF OF y's is y^2
These are the number of x's and y's that each term has.
-3x^2y^2(2x^2y^3+5x-3y)
LETTER B
Answer:
See below
Step-by-step explanation:
Do you mean -12(x+5)=-10?
Divide both sides by -12 -> x+5=10/12
Subtract 5 on both sides -> x=10/12-5 -> x=-4 1/6
So x=-4 1/6
Let me know if this wasn't the right equation
