All right triangles follow the Pythagorean theorem [tex]a^2+b^2=c^2[/tex] where the squares of the two shorter sides of the right angle triangle is equivalent to the square of the longest side.
Squares of the two shorter sides:
[tex]9^{2}+15^{2}=306[/tex]
Square of the longer side:
[tex]17^{2}=289[/tex]
∵ [tex]306\neq 289[/tex], ∴ the triangle is not a right angle triangle.

Lines a and b are parallel. Line c is a transversal. FInd the measures of all angles formed by a, b, and c, given each scenario. One of the angles measures 150 degrees.
Answer:
30° and 150°
Step-by-step explanation:
Given
Parallel lines a and b
Transversal c
Angle = 150°
Required
Determine the list of possible angles
A transversal divides a parallel line into two measure which add up to 180°
Given that one of the angles is 150°, the other angle would be 180° - 150°
Other angle = 180° - 150°
Other angle = 30°
Aside 30° and 150°, there's no other possible angle that can be formed by the given information
Answer:
30 and 150
Step-by-step explanation:
Given

Find the values of x and y.
X= __
Y= __
Answer:
x = 20
y = 100
Step-by-step explanation:
To figure out x do this.
3x + 2x = 7x - 40 (collect like terms)
5x = 7x -40 (subtract 7x on both sides)
-2x = -40 (divide by -2 on both sides)
x = 20
Plug in to get y
Since 7x - 40 and y are vertical they equal the same amount
7(20) - 40 = y (multiply 7 by 20)
140 - 40 = y (collect like terms)
100 = y

Jasmin's dog weighs 62 pounds. Her vet told her that a healthy weight for her dog would be less than or equal to 40 pounds.
Jasmin's dog can lose an average of 3 pounds every week. Write the solution to an inequality that describes all possible number of weeks
z for which her dog can be at a healthy weight.
Answer:
62-3z ≤ 40
Step-by-step explanation:
62 is the starting point. jasmin's dog can lose 3 lbs per week and z represents the number of possible weeks. then we know it has to be less than or equal to 40. so put that there.

Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize. Suppose that Isaac is going to buy 6 boxes of this cereal, and let X represent the number of prizes he wins in these boxes. Assume that these boxes represent a random sample, and assume that prizes are independent between boxes. What is the probability that he wins exactly 2 prizes in the 6 boxes?
Answer: 0.3 on khan academy
Step-by-step explanation: ♂️
The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.
Calculation of the probability:Since Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize this mean
So,
P(box containing prize) = 1/4 = p =0.25
So,
q=1 - p
= 0.75
And total box (n)=6
Let us assume x be number of prize win.
So,
Probability that he will win exactly two prize is
P(X=2)= [tex]\binom {6}{2}(0.25)^2(0.75)^4[/tex]
= 0.2966
=0.30(approx)
hence, The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.

75 – 3.5y – 4y = 4y + 6
y=6
Step-by-step explanation:
[tex]75 - 3.5y - 4y = 4y + 6[/tex]
Collect like terms and simplify
[tex] - 3.5y + 4y - 4y = 6 - 75 \\ - 11.5y = - 69[/tex]
Divide both sides of the equation by-3.5
[tex] \frac{ - 11.5y}{ -11.5} = \frac{ - 69}{ - 11.5} [/tex]
Simplify
[tex]y = 6[/tex]
The value of the y in the given equation is 6.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given that, an equation, 75 - 3.5y - 4y = 4y + 6, we need to find the value of y,
75 - 3.5y - 4y = 4y + 6
Combining the like terms,
75 - 6 = 4y + 4y + 3.5y
69 = 11.5y
y = 6
Hence, the value of the y in the given equation is 6.
