Supplementary angles mean two angles that add up to 180.
180 = 139.2 (angle 1) + x (angle 2)
180 - 139.2 = x (angle 2)
40.8 = x
angle 2 = 40.8
Answer:
40.8°
Step-by-step explanation:
The sum of two supplementary angles is 180°.
180 - 139.2 = 40.8
The measure of it's supplement should be 40.8°.

What is reflection?A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a fixed point set; this set is known as the axis or plane of reflection. A figure's mirror image in the axis or plane of reflection is its image by reflection.
Given that Point E has the same y-coordinate as point D, but the x-coordinate of point E is the opposite of the x-coordinate of point D.
The coordinates are the reflection of each other across the y-axis on the coordinate plane.

Three integers sum to 57. The second integer is twice the first integer. The third integer is seven less than five times the first integer. What are the three integers?
Answer:
a=8
b=16
c=33
Step-by-step explanation:
Let's call the integers a, b, and c. (a is the first, b is the second, and c is the third.)
a+b+c=57
Write the second two sentences as equations.
b=2a
c=5a-7
Plug in these values of b and c to the original equation.
a+(2a)+(5a-7)=57
Solve for a:
a+2a+5a-7=57
8a-7=57
8a=64
a=8
Now, plug in your solution for a into the equations for b and c to solve for them.
b=2a=2(8)=16
c=5a-7=5(8)-7=40-7=33
You can add up your answers for a, b, and c to make sure you're correct.
a+b+c=8+16+33=57

How many ways can 7 students be selected from an organization of 30 to attend a national conference?
Determine the number of possibilities for selection. Express your solution in a complete sentence reflective of the scenario.
The number of possibilities for selection is 2,035,000 ways
This question has to do with the combination
Given the following parameters
Total number of students = 30 students
If 7 students are to be selected from a pool of 30 students, the number of ways this can be done is expressed as:
30C7 = 30!/(30-7)!7!
30C7 = 30*29*28*27*26*25*24*23!/23!*7!
30C7 = 30*29*28*27*26*25*24/7!
30C7 = 10,260,432,000/5040
30C7 = 2,035,800
This shows that the number of possibilities for selection is 2,035,000 ways

In 1999, the nation of Malaysia moved its capital from Kuala Lumpur to Putrajaya because of overcrowding. In 2019, the population of Putrajaya was about 86,900, and in 2020, the population grew to about 110,000.
(a) What was the growth rate (k) from 2019 to 2020?
(b) At that rate of growth, what is the population expected to be in 2024?
(c) If the current growth rate continues, when will the population of Putrajaya reach half a million?
Answer:
A) 1.26582278x or 12.6582278%
B) 282412.759
C) 2027
Step-by-step explanation:
A) 86900 -> 110000
110000 / 86900
= 1.26582278
The growth rate is 1.26582278x or 12.6582278%
B) 110000 -> ...
110000 * (1.26582278)^4
= 110000 * 2.56738872
= 282412.759
(Not sure if your teacher will want you to round this down because 0.759 people don't exist)
C) 110000 -> ... > 500000
We can just go through and slowly increasing
2021:
110000 * 1.26582278
= 139240.506
2022:
139240.506 * 1.26582278
= 176253.804
2023:
176253.804 * 1.26582278
= 223106.08
2024:
223106.08 * 1.26582278
= 282412.758
2025
282412.758 * 1.26582278
= 357484.502
2026
357484.502 * 1.26582278
= 452512.026
2027
452512.026 * 1.26582278
= 572800.031
2027 is when the population will reach 500000.

WILL MARK BRAINLIEST <3 Each of the letters in the word "HANDIWORK" are on separate cards face down on the table. If you pick a card at random, what is the probability that the letter on it will fall between "F" and "Q" in the alphabet?
5/9
3/9
1/2
7/9
The probability that the letter on it will fall between "F" and "Q" in the alphabet is 5/9. Option A is correct.
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given the word "HANDIWORK", the total letters in the word are 9 letters.Total outcome = 9 lettersFor the number of events, we will have to find the letters between F and Q in the "HANDIWORK". The letters are n(E) = {H, N, I, O, K}Hence n(E) = 5Pr(the letter on it will fall between "F" and "Q" in the alphabet) = 5/9
Hence the probability that the letter on it will fall between "F" and "Q" in the alphabet is 5/9

Which scenario provides the most direct application of the Hypotenuse-Leg congruence criteria?
A.) two isosceles triangles congruent bases and base angles
B.) two equilateral triangles, each of which has 60 angles and 3-inch sides
C.) two 45 degrees -45degrees-90degrees triangles with congruent sides opposite to the right angle
D.) two right angles, each of which has a 4-foot side opposite the right angle and a 3-foot leg
The Hypotenuse-Leg congruence criteria is (D) two right angles, each of which has a 4-foot side opposite the right angle and a 3-foot leg
Two triangles are said to be congruent if they have the same size and shape. Hence, corresponding sides and angle are congruent to each other.
The Hypotenuse-Leg congruence theorem states that two right triangles are congruent if the hypotenuse and leg of one triangle is equal to the hypotenuse and leg of another triangle.

Solve for x by writing the equation in exponential form.
log7(2x + 17) = 2
Given :-
log 7( 2x +17) = 2 .To Find :-
The value of x .Solution :-
Given logarithmic equation is ,
[tex]\longrightarrow log_7(2x +17) = 2 [/tex]
As we know that ,
[tex]\longrightarrow log_a b = c [/tex]
can be rewritten as ,
[tex]\longrightarrow a^c = b [/tex]
So , that
[tex]\longrightarrow 7^2 = 2x + 17 [/tex]
Simplify ,
[tex]\longrightarrow 49 = 2x + 17 [/tex]
Subtract 17 from both sides ,
[tex]\longrightarrow 2x = 32 [/tex]
Divide both sides by 2 ,
[tex]\longrightarrow x = 16 [/tex]
Hence the required answer is 16 .
