The hypotenuse of an isosceles right triangle is centimeters longer than either of its legs. Find the exact length of each side.

Varvara68 [4.7K]

Question

The hypotenuse of an isosceles right triangle is 11 centimeters longer than either of its legs. find the exact length of each side.

Answer:

$Hypotenuse:37.56$

$Other\ Legs: 26.56$

Step-by-step explanation:

Let the hypotenuse be y and the other legs be x.

So:

$y = 11 + x$

Required

Determine the exact dimension of the triangle

Using Pythagoras theorem;

$y^2 = x^2 + x^2$

$y^2 = 2x^2$

This gives:

$(11+x)^2 = 2x^2$

Open bracket

$121 + 22x + x^2= 2x^2$

Collect like terms

$2x^2 - x^2 -22x - 121 = 0$

$x^2 -22x - 121 = 0$

Using quadratic formula:

$x = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}$

$x = \frac{-(-22)\±\sqrt{(-22)^2 - 4*1*-121}}{2*1}$

$x = \frac{-(-22)\±\sqrt{968}}{2*1}$

$x = \frac{22\±31.11}{2}$

Split

$x = \frac{22+31.11}{2}\ or\ x = \frac{22-31.11}{2}\\$

$x = \frac{53.11}{2}\ or\ x = \frac{-9.11}{2}$

x can not be negative.

So:

$x = \frac{53.11}{2}$

$x = 26.56$

Recall that:

$y = 11 + x$

$y = 11 + 26.56$

$y = 37.56$

Hence, the dimensions are:

$Hypotenuse:37.56$

$Other\ Legs: 26.56$

Help please, I attached the question. Is it a!?

AVprozaik [17]

Answer:

Step-by-step explanation:

Recall that for a quadratic equation of the form:

$0=ax^2+bx+c$

The number of solutions it has can be determined using its discriminant:

$\Delta = b^2-4ac$

Where:

If the discriminant is positive, we have two real solutions.
If the discriminant is negative, we have no real solutions.
And if the discriminant is zero, we have exactly one solution.

We have the equation:

$2x^2+5x-k=0$

Thus, a = 2, b = 5, and c = -k.

In order for the equation to have exactly one distinct solution, the discriminant must equal zero. Hence:

$b^2-4ac=0$

Substitute:

$(5)^2-4(2)(-k)=0$

Solve for k. Simplify:

$25+8k=0$

Solve:

$\displaystyle k = -\frac{25}{8}$

Thus, our answer is indeed A.

Answer:

t = 1, but please check to see if I correctly interpreted your formatting.

Step-by-step explanation:

The format of the question is too confusing.

I'll assume this is the equation to be solved:

16−2t=t+9+4t

16−2t=t+9+4t

16-9 = t + 2t + 4t

7 = 7t

t = 1
