a) The pairs of proportional triangle is
AB and YZ,
AC and XY,
BC and XZ
b) The fraction of side is
YZ / AB = XY / AC= XZ / BC = 3/4.
c) Yes the similarity of Triangle.
What is Similarity?Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " sign here denotes the resemblance of triangles.
In Triangle ABC and YZX
a) So, the pairs of proportional triangle is
AB and YZ,
AC and XY,
BC and XZ
b) The fractions with your side pairs is
YZ / AB = 30 / 40 = 3/4
XY / AC = 37.5 / 50 = 3/4
XZ / BC = 45/ 60 = 3/4.
c) As, the ratio of sides are proportion.
So, by SSS similarity criteria the triangles are similar.

An event that has probability 1 is said to be
Answer:
Impossible; certain to happen
Step-by-step explanation:
Probability = 0 applies to an event which cannot happen. Example: roll a die and get a 7.
Probability = 1 applies to an even which is certain to occur. Example: roll a die and get a number less than 8.

Question 2 (1 point)
drawing a vowel from letter tiles that spell out MATHEMATICS
chance
Blank 1:
Blank 2:
Answer:
3/ 8 ; 3/8
Step-by-step explanation:
MATHEMATICS
vowels in mathematics = (A, E, I)
letters in mathematics = (M, A, T, H, E, I, C, S)
Probability = required outcome / Total possible outcomes
Required outcome = vowels in mathematics = 3
Total possible outcomes = letters in mathematics = 8
Probability of drawing a vowel letter tiles = 3/8
2.)
Spinner division :
Red = 4 ; white =2 ; green = 1 ; blue = 1
Total divisions = 8
Probability (landing on blue) = number of blue / total
P(landing on blue) = 1 / 8
P(landing on white) = 2/ 8 = 1/4
P(landing on blue or white) = 1/8 + 2/8 = 3/8

7. The population of Flood River City is now 42,000. Experts predict the population will decrease 25% each
year for the next five years. What will be the population in five years?
Answer: The population after five years = 9967
Step-by-step explanation:
The exponential equation for population decay : [tex]P=A (1-r)^t[/tex], where A = initial population r= rate of decay , t= time
Given: A= 42000, r= 25%= 0.25, t= 5
then
[tex]P=42000(1-0.25)^5\\\\=42000(0.75)^5\\\\=42000(0.2373046875)\\\\\approx9967[/tex]
Hence, The population after five years = 9967

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.
Write and solve an equation to determine the measure of angle x.
Answer:
X =50 Y is also 50 since they are vertical angles
Step-by-step explanation:
70+ 60 + X = 180 (the 3 angles form a straigh line = 180 )
130 +X =180
X = 180-130
X=50

Incase you can’t see the picture, it says “Explain how to solve the following equation and check for extraneous solutions: x= square root of -2x+6 then out of square root +3 Please help guys
Answer:
x=3
Step-by-step explanation: too much math to put here
Answer:
x= 3 ; (x=1 is an extraneous solution)
Step-by-step explanation:
-2x+6 is under a square root, so its value must be > or equal to 0
If we solve the inequality
-2x+6 ≥ 0 we obtain
-x+3≥ 0
-x ≥ -3
x ≤ 3
now that we know the possible values of x we can proceed like this:
1) move 3 on the left side of equal and change its sign
x-3 = √-2x+6
2) square the two members of the equation
x^2 + 9 -6x = -2x+6
3) solve the equation
x^2 -4x +3 = 0
(x-3)(x-1) = 0
x = 3
x = 1
4) Check if the solution are ≤ 3 and if they make true the equation
Both solutions are ≤ 3
if x = 3
3 = √-6+6 + 3
3 = 3
true
x=1
1 = √-2+6 + 3
1 = 2+3
1 = 5 false
In conclusion we can say the 3 is a real solution, while 1 is an extraneous solution
In a right triangle one angle measure 28° more than the other acute angle. Use equations to solve for the measures of the two unknown angles.
Answer:
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
Step-by-step explanation:
In the right angled triangle one angle is always equal to 90 degrees.
Suppose <a= 90 degrees
< b= x degrees
< c= x+28 degrees
The sum of all the angles of the triangle are always equal to 180 degrees
therefore
<a+ <b+<c= 90 + x+ x+28 = 180
or
2x= 180- 28- 90
2x=62
x= 31 degrees
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
An acute angle is an angle which has less than 90 degrees in measurement .
Hence both angles of the right angle triangle are acute angles , 31 and 59 degrees.
