Hello from MrBillDoesMath!
Answer:
x = 1/2 (1 +\- i sqrt(23))
Discussion:
x \3x - 2 = (x/3)*x - 2 = (x^2)/3 - 2 (*)
1 \3x - 4 = (1/3)x - 4 (**)
(*) = (**) =>
(x^2)/3 -2 = (1/3)x - 4 => multiply both sides by 3
x^2 - 6 = x - 12 => subtract x from both sides
x^2 -x -6 = -12 => add 12 to both sides
x^2-x +6 = 0
Using the quadratic formula gives:
x = 1/2 (1 +\- i sqrt(23))
Thank you,
MrB
The answer is the one you put that and it says its correct
Answer:
Semicircle
Step-by-step explanation:
As we can see, the arc is bounded by the chord MO
since the chord passes through the center of the circle, we have it that the chord is a diameter
Mathematically, an arc bounded by a diameter represents half of a circle
So we can conclude that the arc MNO in circle C is a semicircle
Answer:
D
Step-by-step explanation:
3 and 1/4 = (3*4 + 1)/4 = 13/4. 3*(13/4) = 39/4 = 9 and 3/4 so it is D
Hope this helps!
Answer:
Part 1) 
Part 2) The measure of the interior angles are 64°-67°-49°
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the value of x
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
In this problem
Solve for x
Combine like terms
Subtract 18 both sides
Divide by 6 both sides
step 2
Find the measure of each interior angle
substitute the value of x in each measure
