Step-by-step explanation:
the 2 angles marked with orange and green are equal becos the question said that the indicated angles are congruent meaning same deg. so 180 - that given angle = the 2 marked angles (based on the rule known as angles on a str line are supplementary)
since the 2 marked angles are same, you can say that d and k are parallel due to the rule of alternate angles

Answer:
Step-by-step explanation:
GIVEN: Suppose that in a certain county 
of voters are registered as Democrats, 
as Republicans, 
as Green party, and the rest are considered Independents. You conduct a poll by calling registered voters in the county at random.
TO FIND: Probability that the first call will be to either a Democrat or a Republican.
SOLUTION:
Lets total population of county be 
.
voters registered as Democrats 
voters registered as Republicans 
voters registered as Green party 
Probability that first call will be to Democrats 
Probability that first call will be to Republican 
probability that the first call will be to either a Democrat or a Republican
Hence the probability that the first call will be to either a Democrat or a Republican is
aApolynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
There are 3 sets of polynomials; LINEAR, QUADRATIC and CUBIC
Linear: 
Quadratic: 
Cubic: 
7 x 500,080=7 x (500,000+80)=7 x 500,000+7 x 80=3,500,000+560=3,500,560
