Answer:
-1 3/ 4
Step-by-step explanation:
a regular pentagon is divided into 5 isoscleles triangles work out the size of angle x angle y angle z
x = 72
y = 54
z = 54
================================================================
The regular pentagon has all five sides the same length. It also has all interior angles the same measure. This leads to y = z. These two angles are the congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides.
The fact that we have a regular pentagon also means that the five triangles shown are identical copies of one another (i.e. they are congruent triangles). Divide the full 360 degree rotation into 5 parts to get 360/5 = 72, which represents the measure of the central angle x.
--------------
For any triangle, the three angles always add to 180. This means,
x+y+z = 180
72+y+z = 180 .... plug in x = 72
72+y+y = 180 ... recall that y = z
2y+72 = 180
2y = 180-72
2y = 108
y = 108/2
y = 54, which is also the measure of angle z as well
--------------
As a quick check,
x+y+z = 72+54+54 = 180
which helps confirm the answer.
explain how you know these figures are similar
Answer:
because of them is bigger than the other one so that means its differ but it has the same length

An air traffic controller is monitoring the altitudes of four planes. The four equations below show y, the
distance in feet of each plane above the ground, after 6 minutes of descent. (Hint: Look at the slopes to help
you.)
Plane A: y = 400t + 12,000
Plane B: y = -800t + 28,000
Plane C: y = -200t +13,500
Plane D: y = -500t + 30,000
a. Which plane is descending at the slowest rate?
b. Which plane began its descent from the highest altitude?
Answer:
Step-by-step explanation:
a. Plane C has the slowest rate of descending.
b. Place D has begun to descend from the highest altitude.
What is the equation of a line in slope intercept form?The equation of a line in slope intercept form is y = mx + b where the slope is m and the y-intercept is b.
The altitude of four planes is represented by y after 6 minutes and t represents time in minutes.
To determine which plane is descending at the slowest rate we have to look for a slope in these four equations which is the least steep or which modulus value is the least.
If we take the modulus of all four slopes 200 is the least value.
∴ Plane C has the least descending rate.
To determine which plane starts descending from the highest altitude we look for the value of y-intercept which is the largest among them and that is plane D.

Write a real life scenario that could model the following relationship:
y=20x+60
Make sure to include what x and y represent in your description.
Answer:
You work for x hours and earn $20 for each hour. You get paid $60 before you come in each day. What is y when you work for x hours?
Step-by-step explanation:
x is the independent variable and can vary. You have to add the $60 in there, too. Adding them together gets you to y = 20x + 60 and this real life scenario works.

What percentage of the Cub Scouts are at least as old as a Bear Scout?
Tigers (6 years old): 19%
• Wolves (7 years old): 36%
Bears (8 years old): 17%
Webelos (9 years old): 28%
.
The percentage of the cub scout which are atleast as old as the near scout refers to percentage of the cub scout which are atleast 8 years old. Hence, the percentage is 28%
The age of Bear scout = 8 years oldCub scouts which are atleast 8 years old :
Webelos = 9 years old Percentage of Webelos = 28%Hence, the percentage of cub scout which are atleast 8 years old is 28%

n
In the figure, lines mand n are parallel to each other. Lines p and q are also parallel to each
m
other. What is the value of x?
Answer:
80
Step-by-step explanation:
in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x
that is
if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees
since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees
therefore y=100
now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees
that is
x+y=180
we know that y = 100
therefore,
x+100=180
collect like terms and
x = 180-100
therefore,
x= 80

Combining like terms on the right side, we have [tex]12x=30[/tex].

Answer:
see explanation
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides )
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the given angles and equate to 540
2b - 90 + 90 + b + 45 + b + [tex]\frac{3}{2}[/tex] b = 540, collect like terms
4b + 1.5b + 45 = 540 ( subtract 45 from both sides )
5.5b = 495 ( divide both sides by 5.5 )
b = 90
then
2b - 90 = 2(90) - 90 = 180 - 90 = 90
b + 45 = 90 + 45 = 135
[tex]\frac{3}{2}[/tex] b = 1.5b = 1.5 × 90 = 135
The angles from least to greatest are
90° , 90° , 90° , 135° and 135°

Enter an equation in point-slope form for the line.
Slope is -4 and (1,9) is on the line.
The equation of the line in point slope form is:
Answer: (y-9) = -4(x-1)
Step-by-step explanation: The format of a point-slope line is y − y1 = m(x − x1), where x1 and y1 are a known point on a line with slope m. Given slope of -4 and a point of (1,9):
(y − y1) = m(x − x1)
(y − 9) = -4(x − 1)
This can be rearranged to the standard form: y = -4x+13
