What is the area of a triangle with vertices (3,0) (9,0) (7,6)
Nezavi [6.7K]

Answer:

The area of the triangle is of 21 units of area.

Step-by-step explanation:

The area of a triangle with three vertices (x_1,y_1),(x_2,y_2),(x_3,y_3) is given by the determinant of the following matrix:

A = \pm 0.5 \left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\1_3&y_3&1\end{array}\right|

In this question:

Vertices (3,0) (9,0) (7,6). So

A = \pm 0.5 \left|\begin{array}{ccc}3&0&1\\9&0&1\\7&7&1\end{array}\right|

A = \pm 0.5(3*0*1+0*1*7+1*9*7-0*7*1-0*9*1-3*1*7)

A = \pm 0.5*(63-21)

A = \pm 0.5*42 = 21

The area of the triangle is of 21 units of area.

How is multiplying exponents (x^2*x^4) different from raising a power to a power((x^2)^4)? Ty =)
Contact [7]

Answer:

When your multiplying exponents in the same parenthasis like x^2*x^4, you'll add the exponents so it will be x^6. If it is outside the parenthasis like (x^2)^4 you'll multiply the exponents so it will be x^8. good luck! :)

Find the value of x and the length of each side ​
AlladinOne [14]

The 3 sides of the triangle are  PR =  8.4, OR =  5.4 and OP =  3.1

Step-by-step explanation:

Step 1 :

Given

PR = 3x - 0.6

OP = x +  0.1

OR = x + 2.4

Also the 2 sides OR and PR are said to be equal.

So we have OR = PR

=> 3x - 0.6 =  x + 2.4

=>  x = 2.4 + 0.6 => x = 3

Step 2 :

we have ,

PR = 3x - 0.6 = 3(3) - 0.6 = 8.4

OR =  x + 2.4 = 3 + 2.4 = 5.4

OP = x + 0.1 = 3 + 0.1 = 3.1

Step 3 :

Answer :

The 3 sides of the triangle are

PR =  8.4

OR =  5.4

OP =  3.1

Evaluate the sine of angle X for the right triangle below.
bezimeni [28]

Answer:

\frac{7}{25}

Step-by-step explanation:

sinx = \frac{opposite}{hypotenuse}

The hypotenuse = 25 since 7, 24, 25 ← Pythagorean triple

Hence

sinx = \frac{7}{25}
