Hi there!
Since we know that the sum of all 3 measures of a triangle is always equal to 180 degrees, and that supplementary angles are equal to 180 degrees when added, we can solve by first finding the supplement to ?.
75 + 40 + ? = 180
180 - 75 - 40 = ?
105 - 40 = ?
? = 75
Now, we find the actual? .
Since 75 + ? = 180,
180 - 75 = 115
? = 115
So, your answer is 115°.
Hope this helps!
Answer:
Infinite many solutions. Any x-value can satisfy the equation.
Step-by-step explanation:
Let's work on simplifying the equation a little to investigate which x-values satisfy it. Start by combining like terms on the left side (6x +4x=10x),
then distribute the factor "10" into the binomial (x+10), obtaining 10x +30.
Now we have the same expression on the left and the right of the equal sign:
10x +30=10x+30. We may subtract 30 from both sides, and obtain 10x=10x, and at this point divide by 10 both sides, and we obtain: x=x
The process is shown below.

x=x is an equation that is verified by absolutely ANY x value on the number line, and there are infinite x-values in the number line.
Therefore there are infinite many solutions to this equation (any x-value will satisfy it).
The answer is P=8Lvf/pieR^4

Answer: 1.95$.
19.50 x .9 = 17.55
19.50 - 17.55 = 1.95
Therefore the answer is indeed 1.95$.
