The size of the angle 'x' is 117°
The external angle of a triangle:An external angle of a triangle is an angle formed by extending one side of the triangle and intersecting with the extension of another side.
In a triangle, the measure of an external angle is equal to the sum of the measures of the two opposite interior angles.
Here we have a triangle
Let the ABC be the triangle as given in the picture
=> ∠A = 38°
From the baseline BC
=> Measure of B = 180° - 101° = 79°
As we know
In a triangle, the measure of an external angle is equal to the sum of the two opposite interior angles
=> x = ∠A + ∠C
=> x = 38° + 79°
=> x = 117°
Therefore,
The size of the angle 'x' is 117°

The sum of two numbers is 8. Two times the larger number plus four times the smaller number is 8. Find the numbers.
Answer: 12 and -4
Step-by-step explanation:
Assume the larger number is x and the smaller one is y.
In that case the relevant simultaneous equations are:
x + y = 8
2x + 4y = 8
Use substitution to find relative value of y:
x + y = 8
y = 8 - x
Use to solve equation:
2x + 4y = 8
2x + 4(8 - x) = 8
2x + 32 - 4x = 8
2x - 4x= 8 - 32
-2x = -24
x = -24 / -2
x = 12
y = 8 - x
= 8 - 12
= -4

At time t=0 seconds, Alice hits the water 2 meters out fromthe edge of the pool at a constant speed of 1 meter per second, which she maintainsthroughout the race. Meanwhile, at t=0, Bob starts off from rest at the pool walland is speeding up.

for the ball to get to the ground the h=0 no hight it is now in the base point.
substitute the value t=0 into the equation we get 64.
since we want to know the time in seconds then we should subtract 60 from 64 (64-60=4)

A turtle travels mile in hour. At this rate, how far can the turtle travel in an hour
1/18 mile
2/9 mile
4 1/5 miles
4 1/2 miles
Answer:
4 1/2
Step-by-step explanation:
The origional question is ¨A turtle travels 1/2 mile in 1/9 hour. At this rate, how far can the turtle travel in an hour¨ To be honest i have no clue how to explain it but that is the awanser.
The turtle will travel [tex]4\frac{1}{2}[/tex] in an hour.
What is proportion?A proportion is an equation in which two ratios are set equal to each other.
Given that, a turtle travels 1/2 mile in 1/9 hour. we need to find, at this rate, how far can the turtle travel in an hour.
We will solve this by using proportionality, since, rate is constant,
Let the turtle travels x miles in an hour,
Therefore,
x / 1 = (1/2) / (1/9)
x = 1/2 × 9
x = 9/2
x = [tex]4\frac{1}{2}[/tex]
Hence, the turtle will travel [tex]4\frac{1}{2}[/tex] in an hour.

Baba Yaga lost her broom somewhere between her hut and Bald Mountain, and wants to get it back. She calculates that with a tailwind of 2 km/h, she can fly from her hut to Bald Mountain in 6 hours. Baba Yaga starts her trip, finds her broom 40 km before Bald Mountain, and turns around and flies home. The entire journey takes 9 hours. Find the speed Baba Yaga flies in quiet weather (with no tailwind or headwind).
Answer:
The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind) is approximately 2.9 km/h
Step-by-step explanation:
In the question, we have;
The speed of the tailwind = 2 km/h
The time it takes Baba Yaga to the Bald Mountain = 6 hours
The location where Baba Yaga finds her broom = 40 km before Bald Mountain
The duration of the entire journey = 9 hours
Let 'v' represent the speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), we get;
(v + 2) × t = (v - 2) × (t - 9)
v·t + 2·t = v·t - 9·v - 2·t + 18
2·t = 18 - 9·v - 2·t
4·t = 18 - 9·v
t = 4.5 - 2.25·v
(v + 2) × 6 = (v - 2) × (t - 9) + 40
6·v + 12 = (v - 2) × (4.5 - 2.25·v - 9) + 40
6·v + 12 = (v - 2) × (-2.25·v - 4.5) + 40
With a graphing calculator, we have;
6·v + 12 + 2.5·v² - 0.5·v - 9 - 40 = 0
5·v² + 11·v - 74 = 0
Using the quadratic formula
v = (-11 ± √(11² - 4·5×(-74)))/(2·5)
v ≈ 2.9, or v ≈ -5.1
Therefore;
The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), v ≈ 2.9 km/h
(10-x)(3x -9)=0
NEED HELP ASAP
Answer:
Step-by-step explanation:
Since the expressions are multiplied, for the product to equal zero, one term or another has to equal 0 because 0 times anything is zero.
(10-x)(3x-9)=0 when
10-x=0, x=10
3x-9=0, x=9/3=3
So there are two solutions when x=3 and x=10

Suzanne can put up 20 feet of fencing in 64 minutes. How many minutes will it take her to put up 35 feet of fencing?
Answer:
112 minutes
Step-by-step explanation:
Suzanne can put up 20 feet of fencing in 64 minutes.
We need to find minutes it will take to put up 35 feet of fencing.
20 feet = 64 minutes
1 feet = (64/20) minutes
For 35 feet,
[tex]35\ feet=\dfrac{64}{20}\times 35\\\\=112\ minutes[/tex]
So, it will take 112 minutes to put up 35 feet of fencing.

Answer:
line k: y = x + 4
line m: y = -2x + 4
line p: y = -6

The equation for each line considering the graph is line k: y = x + 4, line m: y = -2x + 4, line p: y = -6, line r: x = 1
What is a line?An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.
Calculate the slopes of the lines as shown below,
[tex]m = y_2 - y_1 / x_2 - x_1[/tex]
For line k, m = 0 - (-4) / -4 -0
m = -1
Thus, the equation of a line having slope -1 and coordinates (0, 4) can be written as,
[tex]y-y_1 = m(x- x_1 )[/tex]
y - 4 = -1(x-0)
y -4 = -x
y = -x + 4
Similarly, write the equation for lines m, p, and r,
line m: y = -2x + 4
line p: y = -6
