The formula of an area of a triangle:

A_\Delta=\dfrac{base\cdot height}{2}

We have:

base = 10 cm and height = 20 cm. Substitute:

A_\Delta=\dfrac{10cm\cdot20cm}{2}=\dfrac{200}{2}\ cm^2=100\ cm^2

<h3>Answer: 100 cm²</h3>

Area of a triangle = 1/2 base * height

A = 1/2 (10)* 20

A= 5*20

A = 100 cm^2

<h3>Answer:  SAS</h3>

=================================

How to get this answer:

We're told that AD = BC, so that is one pair of sides that are congruent. This forms the first "S" in "SAS"

The "A" refers to the congruent angles, which happen to be angle DAB and angle CBA, both are 90 degrees

The second "S" in "SAS" is the second pair of congruent sides. Those two sides are the overlapping shared side of AB. It might help to peel the two triangles apart to get a better look.

Note how the angles are between the two pairs of sides mentioned.

What is the discriminant of the quadratic equation 0 = –x2 4x – 2?
lyudmila [28]
The answer is down the page under ANSWER. here is a quick explanation first.

okay, i assume your equation is actually like this:

minus x squared plus 4 x minus

note: the proper way to type this electronically is: -x^2 + 4x - 2.



The equation you gave is known as a quadratic equation.

if you think about it, the generic (general) way of writing this quadratic equation is:

ax^2 + bx + c


a, b and c are just numbers

eg.

2x^2 + 7x + 4

looking at the general equation above

a is 2
b is 7
c is 4

you can put negatives in as well, to find out a, b and c

eg

-2x^2 - 6x - 12


so, what is a b and c?

a is -2 (must say its negative)
b is - 6 (must say negative)
c is - 12 ( again, remember its a negative number)

ANSWER

IF YOU JUST WANT THE ANSWER.

THE DISCRIMINANT IS:

4 squared minus (4 times -1 times -2)
this is 16 - 8
solution of discriminant is 8


explanation:

so, now we cleared that up.
in any quadratic equation ( like the equation you gave), the discriminant is (in general)


b2 - 4ac

use this to solve it for any quadratic equation for the discriminant

Step-by-step explanation:

In equilateral triangle, all sides are equal.

{ \sf{perimeter = side + side + side}}

but side = 12 cm

{ \sf{p = (12 + 12 + 12)}} \\ { \sf{p = 36 \: cm}}
