Answer:
Angle 1: 115 degrees
Angle 2: 72 degrees
Angle 3: 57 degrees
Angle 4: 18 degrees
Angle 5: 122 degrees
Step-by-step explanation:
Note: I won’t be finding the angles in order
Angle 3 plus 33 is a right angle which is 90 degrees
So we subtract
90-33=57
Angle 3: 57 degrees
Now angle 2 can be found because a triangle sum of all three angles is 180 degrees
We know 2 75 degrees and 33 so we can add them
75+33=108
Now subtract from 180
180-108=72
Angle 2 is 72 degrees
we can find angle 1 by first finding the missing angle next to it in the triangle
75+40=115
180-115=65
Now we can subtract 65 from 180 to find angle 1
180-65=115
Angle 1 is 115 degrees
Next to find angle 4 we have to find the other missing angle since we already know angle 3 is 57 degrees
The missing angle we just subtract 75 from 180 since the angles are next to each other on a flat plane
180-75=105
And now we add the 2 angles we know
105+57=162
Now subtract from 180
180-162=18
Angle 4 is 18 degrees
Now angle 4 and angle 5 plus 40 degrees is equal to 180 degrees
To find angle 5 we add 40 degrees and 18
40+18
58
Now subtract from 180
180-58
122
Angle 5 is 122 degrees

Solve the system of equation algebraically: y = 2x2 - 5x + 10 and y = 2x + 5.

In order to solve the system of equations, let's equate both values of y and solve for x using the quadratic formula:
[tex]\begin{gathered} 2x^2-5x+10=2x+5\\ \\ 2x^2-5x-2x+10-5=0\\ \\ 2x^2-7x+5=0\\ \\ a=2,b=-7,c=5\\ \\ x=\frac{-b±\sqrt{b^2-4ac}}{2a}\\ \\ x=\frac{7±\sqrt{49-40}}{4}\\ \\ x_1=\frac{7+3}{4}=\frac{10}{4}=\frac{5}{2}\\ \\ x_2=\frac{7-3}{4}=\frac{4}{4}=1 \end{gathered}[/tex]Now, let's calculate the values of y for each value of x:
[tex]\begin{gathered} x=\frac{5}{2}:\\ \\ y=2x+5=5+5=10\\ \\ \\ \\ x=1:\\ \\ y=2x+5=2+5=7 \end{gathered}[/tex]Therefore the solutions are (1, 7) and (5/2, 10).

X'Y'Z' is the image of XYZ under a dilation through point C. XZ=30 and X'Z'=10
What scale factor was used in the dilation?
Answers
The scale factor that was used in the dilation is 3
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, say, 2.
The image of XYZ after dilation through point C is X'Y'Z. X'Z' = 10 and XZ = 30
For Calculating the scale factor, er divide XZ and X'Z'
So, we have :
[tex]\frac{XY}{X'Y'} =\frac{30}{10} =3[/tex]
Hence, the scale factor that was used in the dilation is 3.

Jennifer Lopez met her 10 cousins at a family reunion. The number of male cousins (x) is 2 less than the number of female cousins (y). How many (male,female) cousins were there? (not including Jennifer)
Answers
Answer:
Explanation:
Given that Jennifer Lopez has 10 cousins
The number of male cousins is x
The number of female cousins is y
Since x is 2 less than y, we have:
x = y + 2 ...............................................................................(1)
The total number of cousins is 10, we have:
x + y = 10 ..............................................................................(2)
Substituting equation (1) in (2)
(y + 2) + y = 10
y + y + 2 = 10
2y + 2 = 10
Subtract 2 from both sides
2y = 10 - 2
2y = 8
Divide both sides by 2
y = 8/2 = 2
Substitute the value of y into (1)
x = 2

Answer: No, It is not a right-angled triangle.
Step-by-step explanation:
Find the length of the last side first. To do this, add AB and BC together, then deduct that sum from the 22 cm circumference of Triangle ABC.
ABC - (AB + BC) ⇒ 22cm - (8cm + 5cm)
22cm - 13cm = 9cm
Since the hypotenuse of a triangle is always its longest side, we can be certain that the side we identified is the hypotenuse. The Pythagorean Theorem can now be used to determine whether the triangle is a right triangle.
Pythagorean Theorem: a² + b² = c², where a and b are legs and c is the hypotenuse. The triangle is a right triangle if a2 + b2 do equal c2.
8² + 5² = 9²
64 + 25 = 81
89 > 81
The triangle is not a right triangle, but since a and b are longer than c, we can conclude that it is obtuse.

What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
There are two figure is shown in figure.
Now,
In first figure;
The sum of all the interior angle in a triangle is 180°.
So, We can formulate;
⇒ (6x - 10)° + (2x + 20)° + (3x + 5)° = 180°
Solve for x as;
⇒ (6x - 10)° + (2x + 20)° + (3x + 5)° = 180°
⇒ 6x - 10 + 2x + 20 + 3x + 5 = 180°
⇒ 11x + 15 = 180
⇒ 11x = 180 - 15
⇒ 11x = 165
⇒ x = 15
Thus, The value of the variable x in first figure will be 15.
For second figure;
We can formulate by the corresponding angle of the parallel lines as;
⇒ x + 50 = 70
⇒ x = 70 - 50
⇒ x = 20
Thus, The value of the variable x in second figure will be 20.
Therefore,
The value of the variable x in first figure will be 15.
The value of the variable x in second figure will be 20.
