Answer:

The right angled triangle

soldier1979 [14.2K]3 years ago
3 0

Answer:

It is the right-angled triangle.

Step-by-step explanation:

According to the Pythagorean theorem, a^{2}+b^{2}=c^{2}, which c is the longest side of the triangle.

So, 27^{2}+36^{2}=45^{2} if the triangle is right angle.

LHS=27^{2} + 36^{2} = 2025

RHS=45^{2}=RHS=45^{2} = 2025

∵LHS=RHS

∴It is a right-angled triangle.

Find y when x = 12, if y = 2 when x = 5
AleksAgata [21]
Y = kx
k = y/x
k = 2/12

so when x = 12
y = kx
y = 1/6(5)
y = 5/6

answer

PLS , help me asap :(( , im so frustrated , idk how to do these :c
kolezko [41]

Answer:

y intercept = 5

Step-by-step explanation:

In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

The length of a rectangle is 3 inches more than the width. The area is 10 square inches. Find the dimensions
mr_godi [17]

Answer:

Width = 2

Length = 5

Step-by-step explanation:

let A be the area of the rectangle

   L be the length of the rectangle

   w be the width of the rectangle

<u><em>Formula</em></u>: ‘<u><em>area of a rectangle</em></u>’

A = L × w

…………………………………………………

A = L × w

⇔ 10 = (w + 3) × w

⇔ 10 = w² + 3w

⇔ w² + 3w - 10 = 0  

<u><em>Solving the quadratic equation</em></u> w² + 3w - 10 =  0 :

Δ = 3² - 4(1)(-10) = 9 - (-40) = 9 + 40 = 49

then √Δ = 7

\Longrightarrow w=\frac{-b+\sqrt{\Delta } }{2a} =\frac{-3+7}{2} =2

  or\ w=\frac{-b-\sqrt{\Delta } }{2a} =\frac{-3-7}{2} =-5

-5 is not valid ,because w represents the width

which must be a positive number

Then  w = 2

<u><em>Conclusion</em></u>:

Width = 2

Length = 2 + 3 = 5
