Answer:
Step-by-step explanation:
First, you have to find the degress for m<A.
m<A+ 90+37=180
m<A+ 127=180
then you subtract 127 from both sides.
So, m<A= 53 degress, We already know that m<B is 90,
So let's solve for m<C.
m<C + 53+ 90= 180
m<C+ 143=180
m<C= 37 degress.
Since the triangles are both the same and has the same length and are congruent polygons
m<X=53 degress, m<Y= 90 degress, and m<Z= 37 degress

Determine the value(s) for which the rational expression 5x6x is undefined. If there's more than one value, list them separated by a comma, e.g. x=2,3.
Explanation:
We cannot have zero in the denominator. If x = 0, then the denominator 6x becomes 6x = 6*0 = 0. So we must exclude this from the domain to avoid a division by zero error.
One could argue that the 'x's cancel out when we divide. Yes that's true and [tex]\frac{5x}{6x} = \frac{5}{6}[/tex], but as far as the calculator is concerned, it will not try to simplify the expression (unless it's a specific type of calculator). Instead, the calculator would likely follow the order of operations PEMDAS to try to compute directly. The calculator would hit the stumbling block of dividing by zero and produce "undefined" or "not a number".

Solve for x.
Answer and Step-by-step explanation:
To solve for x, we need to look at 2 deciding factors that allows us to be able to find x.
We are given 2 parallel lines, denoted by the arrow pointing right on the end of both of them, and a transversal line that cuts through the two lines. Because the lines are parallel, the angles that are formed by the transversal like will be equal or correspondent to each other in a few ways.
For the angles we are given, the angles are on the same side of the transversal line, and on the top of their respective parallel lines. Because of this, the angles are equal to each other.
To solve, set the two angles equal to each other.
4x + 20 = 2x + 60
Subtract the 2x from both sides of the equation.
2x + 20 = 60
Subtract the 20 from both sides of the equation.
2x = 40
Divide both sides by 2.
x = 20
x is equal to 20.

Given -
two parallel lines with a transversal.
To find -
to find the value for x.
Concept applied -
Here in the figure, these two angles let's say 1 = 4x + 20° and 2 = 2x + 60° are corresponding angles. And we know that corresponding angles are equal. As all these angles that have the same position in leu the parallel lines and the transversal are corresponding pairs. Therefore, 1 = 2
Solution -
➙ 4x + 20° = 2x + 60°
➙ 4x - 2x = 60° - 20°
➙ 2x = 40°
➙ x = 40°/2
➙ x = 20°
Henceforth, the value of x = 20°.

Jenny has a 12-sided die.
If Jenny rolls the die 180 times, how many times can Jenny predict she will roll a 12?
The prediction of a roll of 12 is the expected value of rolling a 12
Jenny can predict 15 as the number of times she will roll a 12
How to predict the number of rolls of 12?The dice is a 12-sided dice.
This means that the dice has 12 sides.
So, the probability of obtaining a 12 is:
P(12) = 1/12
In a roll of 180 times, the number of times a 12 is expected to show is:
E(x) = np
This gives
E(x) = 180 * 1/12
Evaluate the product
E(x) = 15
Hence, Jenny can predict 15 as the number of times she will roll a 12

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x
f(x) = [tex]\frac{2}{x}[/tex] and g(x) = [tex]\frac{2}{x}[/tex]
Step-by-step explanation:
given f(x) = 2/x and g(x) = 2/x
f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x
g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x
therefore they are inverses
since f(g(x)) = g(f(x)) = x.

Please help with this problem.
Step-by-step explanation:
you should have measured the lengths of the sides and added that information here to the picture.
because we here cannot measure this from a picture that is inclined and has no size scale.
I can give you a hint how to get the angles, when you have all 3 sides :
start with the extended Pythagoras for non right-angled triangles:
c² = a² + b² - 2ab×cos(C)
with c being the side opposite of the angle you are aiming for.
then
2ab×cos(C) = a² + b² - c²
cos(C) = (a² + b² - c²)/(2ab)
for example, to get the angle at T, its opposite side is SE.
cos(T) = (ST² + ET² - SE²)/(2×ST×ET)
you can do the same thing for all 3 angles (you need to always pay attention to what sides you have to use in what combination for the angle).
or you can switch after getting the first angle to the laser of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the disposing angles are always opposite of each other.
for your triangle that looks like
ET/sin(S) = ST/sin(E) = SE/sin(T)
from there (once you have one angle via the Pythagoras approach) you get all other angles.

Rashaad owns a small business selling used books. He knows that in the last week 13 customers paid cash, 50 customers used a debit card, and 53 customers used a credit card. Based on these results, express the probability that the next customer will pay with a debit card as a fraction in simplest form.
Answer:
25/58
Step-by-step explanation: Ok, your step one should be to add all the previous customer values together to see what the total pool of values is. 13+50+53=116, this becomes your denominator. Then, you see that out of these 116 customers in the past week, 50 used a debit card. So based on this data, we can assume that 50 out of every 116 customers will use a debit card. The fraction is thus 50/116. Then it needs to be simplified. Divide the numerator and denominator by 2, and BAM 25/58 is your final answer.
Probability that next customer will pay with debit card is (25 / 58) (simplest fraction form).
What is probability?" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes for a given event."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Given,
Number of customers paid through cash = 13
Number of customers paid through debit card = 50
Number of customers paid through credit card = 53
Total number of customers = 13 + 50 + 53
= 116
Substitute the value in the formula we get,
Required probability = (50 / 116)
= (25 / 58) (simplest fraction form)
Hence, probability that next customer will pay with debit card is (25 / 58) (simplest fraction form).
