The two lines with arrows are parallel, which means angles A and B are supplementary.
So we have
A + B = 180º
(6<em>x</em> - 35)º + (3<em>x</em> + 53)º = 180º
(9<em>x</em> + 18)º = 180º
(9<em>x</em>)º = 162º
<em>x</em> = 18
This means angle A has measure
A = (6<em>x</em> - 35)º = 73º
Answer:
-4
Step-by-step explanation:
4/9 divided by 2/3 divided by 5/6 = 4/5
when you divided by two fractions, you can flip the denominator and numerator and then mutiply
Answer:
D) 1/5 e 1/3
Step-by-step explanation:
You have the following quadratic equation:
(1)
In order to find the values of x that are solution to the equation (1), you first find the solution for k in the following equation:

Next, you replace the previous value of k in the equation (1) and you use the quadratic formula to find the roots:

Then, the roots of the equation (1) are
D) 1/5 e 1/3
