Answer:
C. 49.
Step-by-step explanation:
The measure of the angle below <1 = 68 degrees (vertical angles).
m < 3 = 72 + 68 External angle of a triangle theorem.
m < 3 = 140
3x - 7 = 140
3x = 147
x = 49.
Answer:
C
Step-by-step explanation:
The angle at the top of the triangle is vertical to ∠ 1 and congruent
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 3 is an exterior angle of the triangle, then
3x - 7 = 72 + 68 = 140 ( add 7 to both sides )
3x = 147 ( divide both sides by 3 )
x = 49 → C

There were 54 runners to start a race. In the first half of the race, 1/3 of them dropped out. In the second half of the race, 5/6 of the remaining runners dropped out. How many runners finished the race?
Answer:
6 runners finished the race
Step-by-step explanation:
Total number of runners = 54
In the first half of the race, 1/3 of them dropped out
= 1/3 of 54
= 1/3 * 54
= 54/3
= 18 runners
Runners remaining after first half = total runners - dropped out runners at first half
= 54 - 18
= 36 runners
In the second half of the race, 5/6 of the remaining runners dropped out
= 5/6 * 36
= (5*36)/6
= 180/6
= 30 runners
Runners remaining after second half = runners remaining after first half - dropped out runners at second half
=36 - 30
= 6 runners
Therefore, 6 runners finished the race

I REALLY REALLY NEED HELP ON THIS I DON'T UNDERSTAND IT!!!!!!!!!!!!!!!!!
Answer:
d
Step-by-step explanation:
in order for it to be a triangle the angles have to add up to equal 180
5+75+100=180 so its not a
10+80+90=180 so its not b
20+60+100=180 so its not c
45+45+45=135 so its d because the angles dont add up to 180
50+50+80=180 so its not e
Answer:
D
Step-by-step explanation:
To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

Angles A and B are adjacent angles and are supplementary. The measure of ∠A is (3x+10)∘, and the measure of ∠B is (12x+35)∘.
Write an equation that can be used to determine the value of x.
Enter the correct answer in the box.
Answer:
180=12x+35+3x+10 or 180=15x+45
Step-by-step explanation:
supplementary means that they will add up to equal 180.

Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?
The value of x is -1 and value of y is -1.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are
x+5y=-6...(1)
5x – 3y = -2...(2)
Multiply equation 1 with 5
5x+25y=-30..(3)
Subtract equation 2 and equation 3
5x-3y-5x-25y=-2+30
-28y=28
Divide both sides by 28
y=-1
Now plug in y value in equation 1
x=5-6
x=-1
Hence, the value of x is -1 and value of y is -1.

How many radians is 252°?
Give the exact answer in simplest form
Radian is a more advanced degrees measurement that is easier to use in trigonometry physics etc.
A full circle 360 degrees is 2pi radian.
We just need to find the ratio of 252 degrees to 360 degrees and multiply that by 2pi.
252/360*2pi(rad)
=126/180*2pi(rad)
=63/90*2pi(rad)
=21/30*2pi(rad)
=7/10*2pi(rad)
=7/5*pi (Radian)

What is the solution set of 4x = y and [tex]2x^{2} -y=0[/tex]
A.
{(0.5, -0.5), (2, -8)}
B.
{(0, 0), (2, 8)}
C.
{(1.5, 2), (8, 2)}
D.
{(-1.5, -2), (2, 8)}
Answer:
B.
{(0, 0), (2, 8)}
Step-by-step explanation:
Substitute 4x in for y in the second equation.
[tex]2x^{2} - 4x = 0\\[/tex]
2x(x - 2) = 0
x = 0 or x - 2 = 0
x = 2
Substitute x = 0 and x = 2 in the first equation to get the corresponding values for y
4(0) = y and 4(2) = y
y = 0 or y = 8
