Supplementary angles because because angle 1 + angle 2 = 180° so they form a line
Answer:
x∉R
Step-by-step explanation:
1) Solve the quadratic equation 9x²-18x+14=0 using x=(-b±√b²-4ac)/2a:
x=(-(-18)±√(-18)²-4×9×14)/2×9
2) Evaluate the power, calculate the product and multiply the numbers:
x=(18±√324-504)/18
3) Calculate the difference:
x=(18±√-180)/18
4) The square root of a negative number does not exist in the set of Real Numbers:
x∉R
Given:
A circle is centered on point B.
Points A, C and D lie on its circumference.
If 
measures 40°.
To find:
The 
.
Solution:
Central angle theorem: According to this theorem, the central angle is equal to the twice of inscribed angle on the same intercepted arc.
In the given figure 
is the central angle and is the inscribed angle on the same arc AC.
Using central angle theorem, we get
Therefore, the measure of angle ADC is 20°.
If you make them have the same denominator the fractions would be
12/15 - 5/15=
this equals 7/15 and you can't simplify it.
Answer:
{3, 4, 5, 6, 7, 8, 9, 10, 11}
Step-by-step explanation:
Let integer be x
x > 2 and x < 12
gives
2 < x < 12
All such integers are {3, 4, 5, 6, 7, 8, 9, 10, 11}
