How many sides are on a triangle?

There are 3 sides. If you draw out a triangle, each line is a separate side (a line segment connecting 2 vertices, or points). You can also see in the word "triangle" the prefix "tri-", meaning "three". It refers to the shape having 3 angles, but when there are 3 angles there are 3 sides to make it up. This is true for other shapes too - in a square, there are 4 sides connecting 4 points, and between each side is an angle, creating 4 angles.

Answer:

Three

Step-by-step explanation:

A triangle is a 2-D figure having three sides, three vertices , and three angles formed in it.

The sum of all the three angles in a triangle is 180°

Also, Area of a triangle = $\frac{1}{2}*base*altitude$

Altitude is the perpendicular height of a triangle from the base of it

Perimeter of a triangle= Sum of length of all its three sides

In a right angled triangle the Pythagoras Theorem can be applied to find its third side if two are given:

(Length of Hypotenuse)²=(Length of Base)²+(Length of Perpendicular)²

If we substitute $x=r\cos\theta$ and $y=r\sin\theta$ , we get $r^2=x^2+y^2$ , so that

$z=\cos(x^2+y^2)=\cos(r^2)$

which is independent of $\theta$ , which in turn means the surface can be treated like a surface of revolution.

Consider the function $f(t)=\cos(t^2)$ defined over $0\le t\le1$ . Revolve the curve $C$ described by $f(t)$ about the line $t=0$ . The area of the surface obtained in this way is then

$\displaystyle2\pi\int_C\mathrm dS=2\pi\int_0^1\sqrt{1+f'(t)^2}\,\mathrm dt$

$=\displaystyle2\pi\int_0^1\sqrt{1+(-2t\sin(t^2))^2}\,\mathrm dt$

$=\displaystyle2\pi\int_0^1\sqrt{1+4t^2\sin^2(t^2)}\,\mathrm dt\approx7.4144$

I really need help with this problem steps

Solve for y by setting one equation =to X after that you can substitute the equation into the other one let's set the first one in X= FORM
X-7y=10
-2x+14y=-20

Add 7y to both sides of the first equation to let x stand alone
X=7y+10
Now you can substitute x on the second equation
-2 (7y+10)+14y=-20
Distribute
-14y-20+14y=-20
Add and simplify
Us cancel out =0
-20=-20
0=0
They are the same equations you can also divide the second equation by -2 which would make it look like this
X-7y=10
-2 (x-7y=10)
