Lines y and z are parallel. parallel lines are cut by transversals s and t. the angles formed by lines s, t, and y, clockwise from top left, are blank, blank, (10 x 5) degrees, blank, (4 x minus 7) degrees, blank; formed by s and z are 65 degrees, 1, blank, blank; formed by z and t are 2, blank, blank, blank. what is the measure of angle 2? 6 degrees 11 degrees 28 degrees 37 degrees
The sum of the angle of the triangle is 180 degrees. Then the measure of angle ∠2 is 98°.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
Lines y and z are parallel.
The parallel lines are cut by transversals s and t.
The angles are formed by lines s, t, and y be (10x + 5), a, (4x – 7).
∠1 and (10x + 5)° are equal because they are corresponding angles.
And ∠1 and 65° are equal because they are supplement angles.
Then we have
(10x + 5)° = 65°
10x = 65 - 5
10x = 60
x = 6
Then we have
(10x + 5)° = 10 × 6 + 5 = 65°
(4x – 7)° = 4 × 6 – 7 = 17°
We know that the sum of internal angles of the triangle is 180 degrees. Then we have
∠2 + 65° + 17° = 180°
∠2 + 82° = 180°
∠2 = 98°
The measure of angle ∠2 is 98°.

Sherman counted up all his hockey player
cards and realized he had 100. He recently
purchased a book to organize them that
holds 5 cards on a page. If he puts 5 pages
in a section, how many sections will be have
in his book?
Answer:
4
Step-by-step explanation:
because 5 times 5 is 25 which 25 is how many cards fit in one section so 100-25=75 and so you could say that 100 divided by 25 is 4 so he will need 4 sections hope you find this helpful! :D

find the value of x in the triangle shown below
Answer:
61
Step-by-step explanation:
We see that the triangle is isosceles as the two sides of it are 6.
In an isosceles triangle, you have two sides that are the same and two angles that are the same.
The two congruent angles will be opposite to the congruent sides.
So, we know that both angles must be x.
The Angles of a triangle add up to 180 degrees.
2x + 58 = 180
2x = 122
x = 61 ddegrees
Solution:
We know that:
Sum of interior angles of triangle: 180°We can see that the two lines of the triangle are equivalent.
This means that:
The triangle is an isosceles triangle.The bottom angles must be equivalent.Equation created: 58 + x + x = 180
Simplify the LHS.
58 + x + x = 180=> 58 + 2x = 180Subtract 58 both sides.
=> 58 - 58 + 2x = 180 - 58=> 2x = 122Divide 2 both sides.
2x = 122=> 2x/2 = 122/2=> x = 122/2 = 61A manager is comparing wait times for customers in a coffee shop based on which employee is
working at the register. He tracks the wait time for 100 customers when employee A is working
and 100 customers when employee B is working. The results are shown in the table.
Mean Wait Time Standard Deviation
Employee A
73 seconds
2 seconds
Employee B
74 seconds
4 seconds
Is there is a significant difference between the wait times for the two populations? Use a 0.05
significance level. Assume a one-tailed distribution to calculate your P-value. In this case,
assume that the sample standard deviation is equal to the population deviation.
Using the t-distribution, as we have the standard deviation for the sample, it is found that there is a significant difference between the wait times for the two populations.
What are the hypothesis tested?At the null hypothesis, we test if there is no difference, that is:
[tex]H_0: \mu_A - \mu_B = 0[/tex]
At the alternative hypothesis, it is tested if there is difference, that is:
[tex]H_1: \mu_A - \mu_B = 0[/tex]
What are the mean and the standard error of the distribution of differences?For each sample, we have that:
[tex]\mu_A = 73, s_A = \frac{2}{\sqrt{100}} = 0.2[/tex]
[tex]\mu_B = 74, s_B = \frac{4}{\sqrt{100}} = 0.4[/tex]
For the distribution of differences, we have that:
[tex]\overline{x} = \mu_A - \mu_B = 73 - 74 = -1[/tex]
[tex]s = \sqrt{s_A^2 + s_B^2} = \sqrt{0.2^2 + 0.4^2} = 0.447[/tex]
What is the test statistic?It is given by:
[tex]t = \frac{\overline{x} - \mu}{s}[/tex]
In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.
Hence:
[tex]t = \frac{\overline{x} - \mu}{s}[/tex]
[tex]t = \frac{-1 - 0}{0.447}[/tex]
[tex]t = -2.24[/tex]
What is the p-value and the decision?Considering a one-tailed test, as stated in the exercise, with 100 - 1 = 99 df, using a t-distribution calculator, the p-value is of 0.014.
Since the p-value is less than the significance level of 0.05, it is found that there is a significant difference between the wait times for the two populations.

Triangle ABC is given where m∠A = 33°, a = 15 in., and the height, h, is 9 in. How many distinct triangles can be made with the given measurements? Explain your answer.
Answer:
2 Triangles can be made with the given measurements
Step-by-step explanation:
Start by solving for side b
b = 9/sin33 = appr 16.5
9<15<16.5 there are two possible triangles
sin33/15 = sinB/16.5 = sinB=(16.5sin33)/15
B=36.9, 180-36.9=143.1 Next determine if the angles are correct
36.9+33=69.9 143.1+33=176.1 Both of these are less than 180, two triangles can be drawn.
