The meaning of a quadrilateral inscribed in a circle is that the angles on the opposite vertices are supplementary or in other words equals to 180 degrees.
In this exercise it is asked you to find the measure in degrees of angle A. First of all, you have to find the value of x. To do this you have to select two angles on this case angles A and C.
m<A+m<C=180 Substitute the values of angles A and C
2x+9+3x+1=180 Combine like terms
5x+10=180 Subtract in both sides by 10
5x=170 Divide in both sides by 5 to isolate x
x= 34
Now that the value of x is known, you can substitute it into the expression representing angle A.
m<A=2x+9
m<A=2(34)+9
m<A=77The measure of angle A is 77 degrees.
Hi,
Your answer would be: −2x4+10x3−21x2+19x−4
Hope I could help!~ have a good day/night :]
For this case we have the following function:
y = 1/4 (x + 2) ^ 2 - 7
We derive the equation:
y '= 1/2 (x + 2)
Equaling zero we have:
1/2 (x + 2) = 0
We clear the value of x:
x + 2 = 0
x = -2
Answer:
The equation of the axis of symmetry for the parabola is:
x = -2
Answer:
C
Explanation:
You could solve this in the elimination way that I have been done in here.
I use Jason as an example that he paid $11.84 for 5t ( tacos ) + 1q ( quesadilla )
Therefore we could do the elimination if the taco cost 3.45 x 5 = 17.25, would be over the cost.
-> Cross B answer
Then we take 1.57 x 5 = 7.85. 11.84 - 7.85 = 3.99, which it is not 3.39 => Cross D answer.
Therefore the cost of tacos need to be 1.69 because there have been a repetition in both A& C
1.69 x 5 = 8.45. $11.84 - 8.45 = $3.39 for quesadillas.
Which it proves for the answer is C
Hope I have helping you on this question
