Answer:
x = 6√2, y = 6
Step-by-step explanation:
This is an isosceles triangle as one angle measures 45° and the other is a right angle, so it measures 90°.
Therefore, you know that y will equal 6.
You have to multiply a by √2 to find x.
6 x √2 = 6√2
Hope this helps!
Answer:
x = 6[tex]\sqrt{2}[/tex]
y = 6
Step-by-step explanation:
in a 45-45-90 triangle the two legs are equal, so XY = YZ
also, the leg to hypotenuse ratio is 1 : [tex]\sqrt{2}[/tex]
so x = 6 · [tex]\sqrt{2}[/tex]

One interior angle of a convex polygon (a convex polygon is a polygon where all angles
are less than 180 degrees) is 120 degrees. All the other angles are 130 degrees. How many sides
does the polygon have?
Answers
Answer:
7 sides
Step-by-step explanation:
120 + 130x = 180 * (x+1-2)
120 + 130x = 180x - 180
300 = 50x
x = 6
You get that x = 6, but there is still one angle that equals 120, so you have a 7 sided polygon.

Huy is solving a quadratic equation by completing the square. His first few steps (steps 1-4) are shown below. Which of the following statements is true regarding Huy's work?
Given x2+3x−5=0
Solution x2+3x=5 step 1
x2+3x+9=5+9 step 2
(x+3)2=14 step 3
x=−3±14−−√ step 4(1 point)
Huy is incorrect. He made a mistake in step 1 when he added a 5 to both sides. He should have only added a 5 to the left side of the equation.
Huy is incorrect. He made a mistake in step 4 when he solved the equation (x+3)2=14 for x.
Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.
Huy is correct. He has done a nice job of completing the square.

The true statement will be;
''Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.''
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The quadratic equation is,
⇒ x² + 3x - 5 = 0
Now,
Huy is solving a quadratic equation by completing the square.
The steps are;
The quadratic equation is,
⇒ x² + 3x - 5 = 0
Solution; x²+3x=5 (step 1)
x²+3x+9 = 5+9 (step 2)
(x + 3)² = 14 (step 3)
x = - 3 ± √14 (step 4)
Clearly, In step 2 when add 9 then it not make the square form.
That is,
x² + 3x + 9 ≠ (x + 3)²
Thus, The true statement will be;
''Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.''

Answers
Step-by-step explanation:
Given
Area of a circle (A) = 641 ft²
Circumference (C) = ?
We know
πr² = 641
r² = 641 / 3.142
r² = 204
r = 14.28 ft
Now
Circumference
= 2πr
= 2 * 3.14 * 14.28
= 89.68 ft

A, B, C and D and ADC = 120
Find the value of x.
Answers
Answer:
30 degrees
Step-by-step explanation:
The computation of the value of x is given below:
Given that
ADC = 120 degrees
So ABC = 60 degrees
As the sum of the opposite angles are 180 degrees
And ACB = 90 degrees
Now in Triangle ADC
Angle ACB + Angle ABC + x = 180 degrees
90 + 60 + x = 180
x = 30 degrees

% of 10 =7
Answers
We know that 70% of 100 is 70 but since we are working with 10 we can use a proportion.
However, just by looking at the numbers we can conclude it is 70% because if you take a zero off of 100 and 70 it is still proportionally equal to 100 and 70. Therefore, the answer is 70%.

Breadth is 4cm
Step-by-step explanation:
Perimeter = 24cm
Length= 8cm
let the breadth be x
Perimeter = 2(l+b)
24 = 2(8+x)
24 = 16+2x
24-16 = 2x
8 = 2x
8÷2 = x
4 = x
Therefore, breadth is 4cm

What is the x- value of the midpoint between A (-8,-6) and B (0, 6)?
Answers
Answer:
Step-by-step explanation:
Take average of the x-coordinates of A and B.
(-8+0)/2 = -4
x-coordinate of midpoint = -4
The required x value of the midpoint between A(-8, -6) and B (0, 6) is -4.
Given that,
To determine the x value for the midpoint between A (-8,-6) and B (0, 6).
Coordinate, is represented as the values on the x-axis and y-axis of the graph. Where x coordinate of the graph is called an abscissa and y coordinate of the graph is called ordinate.
The midpoint is that point of the line which has an equal distance from both ends of the line.
the x value of the midpoint between A(-8, -6) and B (0, 6) is given by,
x = ( x1 + x 2) / 2
x = ( - 8 + 0 ) / 2
x = - 8 / 2
x = - 4
Thus, the required x value of the midpoint between A(-8, -6) and B (0, 6) is - 4.
