What shape is the area of the triangle formula derived from?

Answers

Answer 1

Answer:

The area formula can be derived from a triangle of any shape.

The formula is applicable to a triangle of any shape. No matter what is the shape of the triangle, the formula for the area of a triangle will always be:

Area $=(1)/(2)* base* height$

and this formula will give the area of any triangle, whether that be a triangle which has acute angles, or it can be a triangle that has an obtuse angle, or it can be a right angled triangle. The above mentioned formula is applicable in all the cases.

Please note that we can choose any side as the base and the height will be corresponding to the base chosen. The formula can be applied after the base and the height have been identified.

Answer:

x = 7, y = 6

Step-by-step explanation:

solve for y for the first equation

2x + y = 20

-2x -2x , eliminate 2x

y = 20-2x

now that we have found y, substitute the y in for the second equation

-5y = -6x + 12

-5(20-2x) = -6x + 12, we just changed y into 20-2x. remember that we are multiplying all of 20 - 2x by -5

-100+10x = -6x + 12, we multiplied everything from the parathesis by -5

+100 + 100, eliminate -100

10x = -6x + 112

+6x +6x , eliminate 6x

16x = 112 , solve for x

x = 7

then y = 20 - 2x = 20 - 2*7 = 6

check:

2 * 7 + 6 = 20

20 = 20

-5 * 6 = -6 * 7 + 12

-30 = -42 + 12

Determine the density of a liquid that has a mass of 63 g and fills a graduated cylinder to 52 ml

Answers

Answer:

1.211 g/ml

Step-by-step explanation:

Given is a liquid , 63 g in weight and filling up a volume of 52 ml

As we know,

Density = $(Mass)/(Volume)$

Mass = 63g

Volume = 52ml

Density = $(63)/(52)$

= 1.211 g/ml

Thus, density of the liquid having mass 63 g and filling 52 ml is

1.211 g/ml.
