Tell whether the triangle with the given side lengths is a right triangle. Y/N question
Answers
16^2 + 63^2 = 65^2
By this we can obviously say that,
The sum of the squares of the two sides = the square of hypotenuse
Which makes it a right angle triangle.
Answer:
yes , it is a right triangle.
Step-by-step explanation:
according to the pythagoras theorem to be the right angled triangle the sum of square of two smaller sides of triangle must be equal to the square of it's hypotenuse.
Here , 65 is largest side so it is hypotenuse and other two sides are the legs of the triangle.
pythagoras theorem:
a^2 + b^2 = c^2
16^2 + 63^2 = 65^2
256 + 3969 = 4225
4225 = 4225
since both sides are equal it can be concluded that the given side lengths d forms a right triangle.

Step-by-step explanation:
Answer:
-23
Step-by-step explanation:
When you do positive-negative you subtract the 2 numbers then take the sign of the number that had the highest absolute value.
25-2=23
The absolute value of -25 is 25
(|-25| = 25)
And the absolute value of 2 is 2
(|2| = 2)
25 > 2
So it would be -23

What is the image point of (4, -6) after a translation right 5 units and
up 4 units?
Answers
Answer:
Coordinate point of the image is (9, -2)
Step-by-step explanation:
In the coordinate point (4, -6);
=> x-value = 4
=> y-value = -6
We know that the translation of;
=> 5 units right would add 5 to the x-value
(x) + 5 = (4) + 59 <= This is the x-value of the image being created by the translation.=> 4 units up would add 4 to the y-value
(y) + 4 = (-6) + 4-2 <= This is the y-value of the image being created by the translation.Therefore the answer; (x, y) => (9, -2)

A 100 m2hay shed is to be extended to give 475 m2of oor space in total, as shown. All angles are right angles. Find the value of x.
Answers
Answer:
[tex]x = 15.[/tex]
Step-by-step explanation:
Given
See attachment for floor space
Required
Find x
The floor can be partitioned into three space.
The dimension and the area of each space is:
Dimension: 10 by 10
[tex]A_1 = 10* 10 = 100[/tex]
Dimension: 10 by x
[tex]A_2 = 10* x = 10x[/tex]
Dimension: x by x
[tex]A_3 = x* x=x^2[/tex]
So, the total area is:
[tex]Area =100 +10x + x^2[/tex]
Given that:
[tex]Area = 475[/tex]
So, we have:
[tex]100+10x+x^2 =475[/tex]
Rewrite as:
[tex]x^2 +10x+100-475=0[/tex]
[tex]x^2 +10x-375=0[/tex]
Expand
[tex]x^2 + 25x -15x -375 = 0[/tex]
Factorize
[tex]x(x + 25) -15(x +25) = 0[/tex]
Factor out x + 25
[tex](x+25)(x-15)=0[/tex]
Solve:
[tex]x = -25\ or\ x = 15[/tex]
x cannot be negative; So:

Step-by-step explanation:
a rectangle that is not a square
The plane will be rectangular which is not a square. Then the correct option is B.
What is a rectangle?It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
A cube is intersected by a plane from the top edge of one face to the bottom edge of the opposite face as shown.
Let a be the side length of the cube.
The length of the rectangular plane will be
L² = a² + a²
L = a√2
Then the dimension of the plane is 'a' and 'a√2' units.
The plane will be rectangular which is not a square. Then the correct option is B.
