What is the area of a triangle for one of the legs being 3in and the hypotenuse being 9in

elena55 [62]

The area of a triangle for one of the legs being 3 inches and the hypotenuse being 9 inches is 12.727 square inches

Solution:

Given that to find area of a triangle for one of the legs being 3 inches and the hypotenuse being 9 inches

From given information,

Let "c" = hypotenuse = 9 inches

Let "a" = length of one of the leg of triangle = 3 inches

To find: area of triangle

The area of triangle when hypotenuse and length of one side of triangle is given:

$A = \frac{1}{2} a \sqrt{c^2 - a^2}$

Where, "c" is the length of hypotenuse

"a" is the length of one side of triangle

Substituting the given values we get,

$A = \frac{1}{2} \times 3 \times \sqrt{9^2 - 3^2}$

$A =\frac{1}{2} \times 3 \times \sqrt{81-9}\\\\A =\frac{1}{2} \times 3 \times \sqrt{72}\\\\A =\frac{1}{2} \times 3 \times 8.48528\\\\A = \frac{1}{2} \times 25.45584\\\\A = 12.727$

Thus area of triangle is 12.727 square inches

Point N has coordinates (-1 , 2) point Q is symmetric to point N with respect to the line y=x what are the coordinates of of poi

kykrilka [37]

Answer:

Q=(2,-1)

Step-by-step explanation:

We are given point as N=(-1,2)

Point Q is symmetric to point N with respect to line y=x

we know that any point symmetric with respect to line y=x means inverse of that point

For example: If we have to find symmetric about y=x line of point (a,b)

a changes to b

and b changes to a

so, symmetric of (a,b) with respect to y=x line would be (b,a)

We have point N(-1,2)

-1------>2

2----->-1

so, we get point as

Q=(2,-1)
